An Overview of Strum Electric 19 2 An Over view of Strum Electric Strum Electric is a synthesizer which was designed with the goal of enabling keyboard players to easily create realistic guitar tracks. This is a task which is usually difficult to achieve due to the very dif ferent nature of these two types of instruments.
20 An Overview of Strum Electric 2.2 Strumming On a guitar, notes and chords are triggered by the action of the picking hand (usually right hand). The resulting sound is very typical of a guitar as the guitarist triggers the strings sequentially , more or less rapidly , with an up and down motion of the hand.
2.4 Signal Flow 21 Figure 8: Graphical user interface of Strum Electric GS-1 . the vibration signal of the individual strings of the guitar . The motion of the strings is the input signal of the pickup module which reproduces the ef fect of single coil or humb ucker -fitted pickups.
22 An Overview of Strum Electric Figure 9: General architecture of Strum ..
K eyboard Layout 23 3 K eyboard Lay out Strum reacts to MIDI signal differently than a traditional synthesizer . It uses a special ke yboard layout and associates signals from standard MIDI controllers with specific ef fects or techniques on the guitar .
24 Keyboard Lay out 3.2.2 Palm Muted Downstr oke and Upstr oke Palm muting is a technique which consists in partially muting the strings with the help of the picking hand by letting it lightly touch the strings near the bridge. The pick (or fingers) is then dragged across the strings in a do wnward or upward motion.
3.3 Pitch Bend Wheel 25 • MIDI note 77(F5): Alternate bass . When the chord played by Strum is not inv erted and the chord includes a fifth (natural, lowered or raised) then the alternate bass is the fifth.
26 Keyboard Lay out 3.4 Aftertouch In Strum , bending can be controlled using monophonic aftertouch (also kno wn as channel pressure on certain controllers). The pitch of the note can be increased in this way by up to one tone depending on the settings of the Bend control of the Aftertouch section of the interface.
3.6 Hold Pedal 27 Figure 10: Sections of the MIDI ke yboard as used by Strum ..
28 Playing Strum 4 Playing Strum Strum can be played in dif ferent w ays, directly from a MIDI k eyboard or using MIDI loops. In this section we describe these different approaches an ho w to reproduce specific techniques used by guitar players. W e conclude this section by describing the dif ferent v oicing options used by Strum .
4.2 Playing with A uto-Strum 29 4.2.2 Chord Change Music eng ra ving by Lil yPond 2.
30 Playing Strum 4.2.4 Hammer -On and Pull-Off Hammer-on and pull-of f are playing techniques used by guitar players to play legato or grace notes. The hammer-on ef fect is obtained by first picking a note and then hammering down another finger onto the same string at a higher fret.
4.3 Using the Strumming K eys 31 In the case where only one or two notes are played on the ke yboard, the notes can be triggered from both the do wnstroke or upstroke strumming key and the Range parameter is ignored.
32 Playing Strum Music eng ra ving by Lil yPond 2.10.33—www .lil ypond.org Figure 16: Scratching with the arp ke ys. higher or the same note as the bass key (arp 6 k ey). The most useful arp ke ys are therefore usually the bass, arp 4, arp 3 and arp 2 keys (E5, G5, A5 and B5).
4.4 Specific T echniques 33 4.4 Specific T echniques 4.4.1 T rills This technique consists in switching rapidly between two notes by using hammer -ons and pull-of fs. W ith Strum , a trill is played by holding the first note and depressing and releasing the second note.
34 Playing Strum Another technique which can be used to obtain partial strums consists in releasing strumming ke ys before the strum is completed. In this way , the strings still not strummed, are not played.
4.5 Using MIDI Loops 35 When the A uto-Strum mode is switched on , one first plays the note which should not be bended and then the second one. The bending effect is then obtained by moving the pitch wheel or using the aftertouch.
36 Playing Strum mode of f , chords are then triggered follo wing the pattern of strumming keys in the MIDI loop. In other words, chords are plucked on the ke yboard and strumming patterns are applied to them through the MIDI loop player . Note that loops are note limited to strumming keys and can also include melodies and chords.
4.6 Chord V oicing 37 4.6 Chord V oicing On the guitar , there are usually many dif ferent w ays to play the same chord. Each of these positions or voicing sounds differently and suits dif ferent musical styles. The specific voicing chosen by Strum for a chord depends on the T ype parameter from the Chor d section of the interface.
38 Playing Strum type allows one to play chords on the keyboard using any voicing and still obtain a guitar chord in root position. Finally , the Playing P osition parameter from the Chord section allows one to specify the lo west fret on which the lowest note of a chord should be played.
Presets and MIDI maps 39 5 Pr esets and MIDI maps Strum Electric comes with se veral factory presets cov ering a wide range of sounds. This collection of presets lets you play and familiarize yourself with this synthesizer without having to tweak a single knob .
40 Presets and MIDI maps 5.1.2 The Program list Presets are loaded into the synthesis engine of Strum Elec- tric from a list of 128 numbered presets called programs. The name of the current program and its number are displayed in the left of the toolbar at the top of the application window .
5.3 Editing and Sa ving Presets 41 • In the bro wser , double-click on a preset icon. • Drag and drop presets from the bro wser onto the Strum Electric interface. • Select a preset by clicking on its icon and use the Enter key from the computer keyboard.
42 Presets and MIDI maps by using the Redo command from the Edit menu or the Ctrl-Y/Apple-Y command. The number of Undo le vels is unlimited and this command is effecti ve on any control of the interface but not on the dif ferent Sav e commands.
5.5 Organizing the Pr eset Library 43 5.5.2 Copying and Moving Pr esets and folders Presets and folders can be copied and mov ed from one location to another . First select an item by clicking on its icon and use the Copy command from the Edit menu (Ctrl-C/Apple-C shortcut) in order to copy it.
44 Presets and MIDI maps 5.5.6 Locating a Preset in the Br owser It might sometimes be helpful to locate in the preset library the preset currently being played or in other words, that corresponding to the current program.
5.8 Backuping Presets and MIDI Maps 45 5.8 Backuping Presets and MIDI Maps There are basically two ways to backup your presets and MIDI maps: exportation and database backup. The database backup is more efficient when there is a lar ge number of elements to backup.
46 Presets and MIDI maps ho wev er , as recovering material from this backup file will remov e the factory library which you hav e just installed and force you to redo the operation. Using the Export command before restoring the factory library is much simpler .
Parameters 47 6 Parameters This section can be used as a reference on the different controls appearing on Strum ’ s graphical interface. W e begin by describing the behavior of the different types of controls appearing on the interface 6.1 General Functioning of the Interface 6.
48 Parameters 6.1.3 Drop-do wn Menus and Displays Clicking on a display with a small down-pointing triangle on its right, such as the T ype control of the Multi-Effect module, re veals a drop-do wn menu with a set of possible settings for the control.
6.2 The Guitar Modules 49 The Pick/Fingers , Strings , Hammer -On , Palm-Mute modules are related to the modeling of the indi vidual strings of the guitar . The Pickups module on the right of the guitar shape represents the action of pickups and allows one to ajdust their volume and select different combinations of pickup positions.
50 Parameters 6.2.2 The Pick/Fingers Module The Pick/F inger module allo ws one to control the excitation of the string with a pick or fingers. The Edge parameter is used to control the rounding of the edge of the plectrum. T urning this clockwise increases the sharpness of the edge resulting in a brighter sound.
6.2 The Guitar Modules 51 6.2.4 The Palm-Mute Module Palm muting is a technique used by guitar players to muf fle the strings slightly while simultaneously playing the strings with the picking hand. It is obtained by letting the side of the picking hand touch the strings just before the bridge.
52 Parameters 6.3 The Amplifier Module Strum Electric is equipped with a v ersatile 2-channel amplifier with speak er cabinet and spring re verb . With relati vely fe w parameters, this amplifier module allows one to obtain a rich v ariety of sounds for dif ferent music styles.
6.4 The Multi-Effect Module 53 6.4 The Multi-Effect Module The Multi-Effect module allo ws one to process the out- put signal from the guitar and the amplifier .
54 Parameters adjust the ratio of “dry” and “wet” signal in the output signal from the module. When the knob is adjusted in the left position, only the original or “dry” signal is sent to the output while in the right position only the processed or “wet” signal is sent to the output.
6.4 The Multi-Effect Module 55 Auto W ah effect the value of the center frequency increases from the v alue fixed by the F r eq knob . T urning this knob clockwise increases the e xcursion of the center frequency . Finally , the Rate knob controls the frequency or rate of the modulation of the center frequency of the filter .
56 Parameters 6.4.7 T remolo The T r emolo ef fect introduces a low frequency modulation of the amplitude of the sound. When the ef fect is used in stereo mode, the sound also bounces with a 180 de gree phase shift from left to right. The Shape parameter is used to adjust the shape of the wa veform which creates the tremolo ef fect.
6.5 Edit Mode 57 Finally , note that some of the parameters are framed by a lighter color background. This simply means that these parameters can be controlled from the general vie w obtained when clicking on the All button.
58 Parameters When these knobs are turned fully to the left, the string vibration is perfectly harmonic. T urning the knobs clockwise increasingly detunes the partials to ward higher frequencies resulting in a more dissonant sound.
6.5 Edit Mode 59 The excitation force produced by the plectrum when interacting with the string is determined by the J ut , Speed , Stiffness and Damp- ing parameters. The Stiffness and Damping parameters determine the flexibility of the plectrum or in other words the resistance it ex- erts against the string.
60 Parameters 6.5.3 The Hammer Module The Hammer module is used to control hammer-on et pull-of f effects as e xplained in section 6.2.3. In Strum , hammer -ons and pull-of fs are triggered when le gato playing on the k eyboard is detected. The two parameters of this section are T one and Amp .
6.5 Edit Mode 61 6.5.6 The Pickups Module The Pickups module simulates the action of the pickups on the guitar . There are two pickups in Strum , labeled Nec k and Bridge , which can be adjusted in various ways in order to obtain tonal col- ors of different guitar types.
62 Parameters 6.6 Perf ormance P arameters 6.6.1 Chord Display The Chord Display is where Strum displays the name of the detected chord or note and the corresponding voicing selected.
6.6 Perf ormance Parameters 63 lo west note of the guitar voicing is always the root of the chord played on the keyboard and de- tected by Strum . In lowest position, the lo west note of the voicing follows the lo west note played on the keyboard.
64 Parameters possible to scan the loops in the same folder using the skip forwar d and skip backwar d buttons. The loops are scanned in alphabetical order starting from the currently loaded loop. Once a loop has been selected, it might be necessary to modify it.
6.6 Perf ormance Parameters 65 The Range parameter under velocity in the Strumming section allo ws one to modulate the num- ber of strings played with the MIDI v elocity signal receiv ed by the program. This is used to emulate the fact that the number of strings in a chord played by a guitarist may vary depending on the in- tensity of the playing.
66 Parameters 6.6.7 Aftertouch In addition to the pitch wheel, monophonic aftertouch (channel pressure) can be used to control a bending ef fect. The depth of the ef fect is controlled using the Depth knob from the Aft. T ouch section. In its center position, the depth is equal to 1 semi- tone.
Utility Section 67 7 Utility Section The utility section is located at the top of the Strum Electric interface and it includes important Strum parameters and monitoring tools. 7.1 The MIDI LED The MIDI LED blinks when the synthesizer recei ves MIDI signal.
68 Utility Section 7.6 Lev el Meter The level meter allows one to monitor the RMS (root means square) lev el of the left (L) and right (R) output channels from the synthesizer .
T oolbar 69 8 T oolbar The toolbar at the top of the Strum Electric interface window allows you to monitor important information related to your current set-up. 8.1 Program Display Located on the left of the toolbar , displays the number and name of the program currently loaded in the synthesis engine.
