Slider tricks with running sequencer

UDO Audio Gear Tips & Tricks
1

Here are some performance tips for using sliders to introduce variance when using the sequencer. I’ve included a sound demo below which demonstrates how to perform them on a running sequencer.

Inital synth setup for those who wish to recreate the sound

LFO1:

  • Looped sawtooth at fast rate

LFO2:

  • Medium vibrato on DDS1+2

DDS Modulator:

  • PWM set to full with LFO1 as source.
  • PW set to 0.

Oscillators:

  • DDS1 set to alternative waveform 12. Octave 32.
  • DDS2 set to pulse waveform. Octave 16.
  • Sync on.
  • Drive set to 1
  • Keytrack set to half
  • Mixed at 35%

Voice setup

  • BINAURAL turned off.
  • LFO1 LHPHASE set to 0.

Envelopes:

  • Plucky ENV1 and ENV2 with long release.
  • ENV1 inverse modulates ENV1-D and ENV2-D for more exponential response.
  • ENV1 looped with keytrack for ratcheting effect.

Sequencer:

  • Sync on

Effects:

  • Internal delay used
  • External reverb used

Slider techniques how they appear and are used in the sound demo

Bar 01:

  • no slider changes

Bar 02: slowly raising DDSMOD-ENV1

  • sync licks

Bar 03: slowly raising PORTAMENTO

  • glides between lower-higher notes

Bar 04: slowly raising DDSMOD-CROSSMOD + VCF-DDS2

  • more crunch and chaos

Bar 05: slowly raising VCF-FREQ while lowering VCF-ENV1

  • smooths plucky envelopes

Bar 06: instantly raising ENV1-A and ENV2-A

  • smooth note transitions

Bar 07: slowly raising VCF-RES

  • accentuates oscillator and vcf modulations
  • significantly increase in loudness. can be handled with a compressor if needed.

Bar 08/09: slowly lowering DDSMOD-CROSSMOD and VCF-DDS2

  • smooth oscillator and vcf modulations

Bar 10/11: slowly lowering VCF-FREQ and VCF-RES

  • use filter to simulate fadeout

An additional example with sequencer in SYNC and some swing. ENV1-HOLD is slightly delayed for creating a rythmic pattern. ENV1 has a sharp curve (A=0 D=0 S=5% R=100%) for getting a snappy pulse. VCF RES is also touching the threshold near self-oscillation which brings out all interesting nuances in FREQ modulations.

In addition: LFO1 is using the free running tip with random mode and delay for fade-in. LFO1 also get synced from sequencer. Delay is also syncronized.

Rest of performance is just waffling around with VCF modulation sliders + changing octaves on oscillators trying to discover interesting sounds. Reverb was also applied.

btw, I would also had liked to use the oscillator SYNC mode but it resets the delay temporary. Think this was a safeguard against delay running amok. Would have been nice if it could be “adjusted” back.
