Global Parameters Mopho’s Glob al paramete rs affect all prog rams global ly. Exam ples include MIDI channel and fine tune. To edit the Global parameters, hold down the Program switch until Global Parameter is displayed. The Param 1 knob changes the global pa ramet er and Param 2 knob and increment and decrem ent buttons change the value.
MIDI Out Select: Out, Thru— MIDI O ut can be s witched t o MIDI T hru to daisychain multiple MIDI devices. Poly Chain: Off, Out 1, Out 4, Out 5, Out 8, Out 12, Out 16 —Used to exp and the polyphony via the Poly C hain output an d one or m ore DSI synt hs—Mopho, Tetra, or Prophet.
arpeggiator. Mopho ca n be confi gured for us e with either normall y open (+) or normally closed (-) footswitches. When set to Arp+ or Arp-, th e footswitch will act as a sustain pedal when the Arpeggiator i s off. Pedal: see table — Sets the destination for the Pedal/CV input.

Oscillators The Oscillators section contains the primary controls for Mopho’s two digitally controlled analog oscillators or DCOs. “Digitally controlled” does not mean the oscillators themselves are digital, just that the oscillators’ frequencies are under digital—rather than voltage—co ntrol.
wave, higher values widen it. At the extreme values, the pulse goes completely flat, which allows for some interesting possibilities with pulse width modulation. 50 Pulse Width 09 9 Glide: 0...127 —Sets the oscillator glide ( portam ento ) rate. Glide can b e set independently for each oscillator.
Glide Mode: FixRate, FixRate A, FixTime, FixT ime A —Determines how the oscillators respond when Glide is on. FixRate: Th e time to transition between notes varies with the interval between the notes; the greater the interv al, the long er the transition time.
Mixer The Mixer section balances the levels of the outputs of the Oscillators section and noise ge nerator, a nd the Audio In/feedback lo op before r outing the s ummed signals to the low-pass filter. Mix: 0...127 —Mixes the outputs of oscillators 1 and 2 in varying am ounts.
Filter Mopho features a selectable 2- or 4-pole, low-pass filter. 4-Pole —Selects the filter configuration. Wh en lighted, the filter is in 4-pole mode. A 4-pole, low-pass filter rolls off frequencies above the cutoff frequency at a slope of 24dB/octave.
Envelopes Mopho has three 5-stage (Delay + AD SR) envel ope gene rators. T wo are dedicated—one to the filter and the other to the amplifier—and the third is assignable to any modul ation desti nation. Envelope Select —Selects the envelope to edit.
LFO Mopho has four low frequency oscilla tors (LFOs). The LFOs can be free- running, synced to k eystrokes, or synced to the sequencer an d MIDI clock. To edit the LFO parameters, choose LFO in the Modulation section. LFO Select: 1, 2, 3, 4 —Chooses the LFO to edit.

Sequencer For many musicians, the term sequence r has becom e synonym ous with M IDI sequencer; that is, a com puter-based ap pl ication or dedicate d hardware device for recording and play ing back notes and per formance gestures via MI DI. But sequencers were around long before MIDI.
does not respond to MIDI start/stop/con tinue messages, but it can still sync to an external clock. Simply turn on the sequ encer and then play and hold a note to start. Or use t he Push It button’s to ggle f eature to latch a note on with one push and release it with another; in this case, the Push It button is essentially a Start/Stop control.
Sequence one has an add itional value, Rest, that appears in the list after Reset. Rest prevent s the envelope s from bei ng gated by the correspon ding step, so a rest in sequence one a ffects all four sequence s. If the sequences are t he same length, rests will occur in the sam e place in all four sequences as they loop.
To avoid ha ving to h old a key dow n, set the Push It Mo de (Misc. Parameters) to Toggle. Then use Push It t o start and stop the sequencer. You may also want t o change the Push It Note, the BPM, and the Clock Divide. 5. Choose a destinatio n for the sequence.
Note: Depe nding up on the BPM an d Clock Di vide setti ngs, the slew rate can actually exceed the time the e nvelopes are gated on, causing a step i n the affected sequence to not reach its set value. For exam ple, if Slew is applied to oscil lator freque ncy, high Slew values m ay cause a step to sound flat or sharp.
Modulators Modulators lets you c onfigure t he modulati on routi ng and am ount for M opho’s four gene ral-purpose m odulation slots. Since each Mo pho modulat ion source has a single dest ination, .
Miscellaneous Modulators There are certain standard c ontrollers that Mopho consigns to de dicated modulators, things li ke mod wheel, pressure ( aka aftertouc h), and velocity .
Clock The Clock sect ion contains t he control s for the internal clock tem po and the note value for the a rpeggiato r and seque ncer (and LFO, when Cl ock Sync i s on). There are also switches to t urn the arpe ggiator and se quencer on and off. Arpeggiator —Tur ns Mopho ’s arpeggiator on and off.
The Arpeggiat or can also be latched wi th a footswi tch connect ed to the Sustai n jack. See “Sustain” in Glo bal Parameters on page 9 . The Arpeggiat or (and Se quencer) ca n also sync t o MIDI clock from an ex ternal sequencer or other de vice.
Miscellaneous Parameters Miscellaneous Paramete rs groups toget her pr ogrammabl e parameters t hat do not conveniently fall in to any obvious section or, if they do, are p arameters that are less frequently used. They are impor tant, but generally not required for performance.
droning sounds, or possibly when using Mopho to process ex ternal audio, turn the VCA Level up. Push It Mode: Normal, Toggle, Audio In— When set to Normal, Push It respo nds like a key: press it and a note plays, release it and th e note ends. But when set to Toggle, Push It turns the note on with one pre ss and off with a second press.

Using USB Mopho’s USB 2.0 port enables bi directional MIDI comm unication wi th a computer. A M IDI interface and MIDI ca ble s are not necessary, just a USB cable. Mopho i s a Class Com pliant USB device. That m eans it does not requi re any additional drivers to be installed to communicate with a Mac or Windows computer.
Windows Vist a and Window s 7 behave t he same as XP, but the de vice name i s DSI Mopho rat her than USB Audio Device. In Windows, if you unplug the USB cable an d plug it back in while a progra m has the Mopho port open, you may hav e to resync.
Using Audio In The Audio I n jack on Mo pho’s rear panel can take au dio from a variety of sources, including line lev el signals and guitars. But what happens to it once its inside and how do you get it ou t again? Simply plugging a gu itar in does not mean you will actually hear something wh en you play it.
Using Poly Chain Mopho’s Poly Chain output enables it to be connected t o other DS I synths f or up to 17-voice polyphon y. Products that can be chained include the Tetra, Prophet '08 (mod ule and keyboard) , desktop M opho, and a seco nd keyboard M opho.
Note : If sy ncing to an ext ernal M IDI clock, s et MIDI Cloc k (Global menu) on the master and any intermediate units to MIDI In/Out. Set the last instrument in the chain to MIDI In. When Poly Chain is set to Off, the Poly Chain MIDI out jack simply duplicates the MIDI out jack.

Support Troubleshooting Here are a few suggestions for re solving problems that may occur. The sequencer has stop ped running. Make sure Clock in the Global menu is set to Internal. Some of the progr ams sound different. Check the Mod Wheel position. The Mod Wheel can do a lot more than just ad d vibrato.
