Don’t forg et you get a free edito r for Mac OS or Windows with your purchase. Download it from ww w.soundtower.com/mopho. I should mention that th is manual does not include ex planations of basic an alog synthesizer function s. It assumes you already know what an oscillator is, how a low-pass filter affects the sound, what an ADSR envelop e loo[...]

Getting Connected Mopho has se veral input s and out puts on its back panel. Power Input — Conn ect the power supp ly included with your Mopho. Th e power supply comes with different AC adap tor prongs that enable it to work almost anywhere in the worl d. If for whatever reason you ne ed to use a different supply, it must match the specifications[...]

Audio can also be used to adva nce the sequencer when Seq Trigger is set t o Audio In. See Sequencer on page 21 for more inform ation. Left Out/Right Out — Mopho’s unbalanced left and right outputs. Phones — A ¼ inch stereo headphone jac k. 4[...]

Basic Operation If you’re fam iliar wit h analog, subt ractive sy nthesis there s houldn’t be anything that looks terr ibly foreign or stra nge abou t Mopho’s front panel.

Turn Compare off to return to the edited version. Com pare can also be used to audition write destin ations when moving a program. Write —Press Write to save the program and write any edits to [...]

Modes of Operation Mopho has three operating modes: progr am, edit, and global. In program mode, Param 1, Para m 2, and Inc/ Dec are used to change from one saved program t o another. As soon as a ny of the programm able parameters are edited, that parameter is displayed on the LCD, with the programmed value on the top line, and the new, edited val[...]

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. The advantage to th at is that the tuning i[...]

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. Low va lues are faster. See also “Glide Mod e?[...]

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. The glide rate is fixed. FixRate A: The same as FixRate, but gl ide is only applie d wh[...]

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. A setting of 0 is equivalent to 100% oscillator 1 and 0% oscillator 2 .[...]

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. When the light is off, the filter is in 2-pole mode and has a slope of 12dB/octa ve and a mor[...]

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. When all three are lighted, the other envel ope param eters control all three e nvelopes sim ul[...]

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. Mopho’s sequencer is much mo re like the origina l analog seq[...]

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. If the sequences are dif[...]

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. 6. Use the Step and Value controls to enter th e desired values. As the sequence loops,[...]

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. If that’s not what you want[...]

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, the four general purpose m odulators p rovide a way t o send a m od source (such as a sequen ce or LFO) to additional destinations, with a different a[...]

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 . The most obvious benefits to doi ng this is it provides a s hortcut to setting up commonly used control lers and it frees up the four ge neral-pur pose mod sl ots for othe[...]

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. T he tempo and note value are determined by t[...]

That usually means going to the USB Audi o Device ( or DSI Moph o) Properties, a s in the proce dure a[...]

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.
