To avoid having to hold a key down, set the Push It Mode (Misc.

Parameters) to Toggle. Then use P

USH

to start and stop the

sequencer. You may also want to change the Push It Note, the BPM,

and the C

LOCK

IVIDE

5. Choose a destination for the sequence.

6. Use the S

TEP

and V

ALUE

controls to enter the desired values.

As the sequence loops, you will hear your edits.

7. Choose another sequence and follow the same basic steps until you’re

happy with the results.

8. Dont forget to write your edits to memory! Sequences are saved with

the related program. Just press W

RITE

and then Y

to save the

program and sequences.

More Sequencer Parameters
The previous section covers the basics of sequencer programming, but there are

some additional parameters that affect the sound and user interaction with the

sequencer.

Slew
In modular analog synthesizers, a lag processor or slew limiter is used to create

a time-varying change—a smooth transition—between successive, discrete

control voltage levels. The rate of change is called the slew rate and one

common application is to create a glide (aka portamento) effect between notes.

Among the possible destinations for Mopho x4 sequences two and four is a

sequence-only parameter called Slew. Slew behaves a little differently from the

other modulation destinations, in that it is not really a destination at all; instead,

it affects the sequence above it. That is, if Slew is the chosen destination for

sequence two, it controls sequence one, and Slew in sequence four controls

sequence three.

In Mopho x4’s sequencer, Slew sets the slew rate between the previous step’s

value and the current step’s value when the step is gated on. Confused yet? This

should help: let’s say sequence one is routed to oscillator frequency and

sequence two to Slew. Increasing the Slew value for step four will cause the

oscillator frequency to glide from the step three value when step four is gated

on. The higher the Slew value, the slower the slew rate. And the slew rate can be

different for each step. But its not just for oscillator glide. Slew can be applied to

any of the destinations. For example, sequence three could be routed to filter

cutoff with Slew in sequence four used to create a less abrupt transition from

one step to the next.
