ALM Busy Circuits

A dual 12-bit digital wavetable drum voice with full voltage control and an analog EQ output path; twin voices are independently triggered and share pitch and envelope parameters of a swept wavetable oscillator, with voice 1 passing through a voltage-controlled analog tilt EQ and voice 2 through a digital wavefolder.1130

Capabilities 5

Drum Voicedrum-voice
Dual 12-bit digital wavetable drum voices independently triggered and output, with shared pitch sweep and envelope parameters.1130
Tilt EQtilt-eq
Voltage-controlled analog tilt EQ on voice 1 output path, also accepts an external mix input.1130
Wavefolderwavefolder
Digital wavefolder on voice 2 output adds brightness and harmonic complexity up to noise.1130
Waveshaper / Wavefolderwaveshaper
1130
Wavetable Oscillatorwavetable-oscillator
Ramped wavetable oscillator sweeping between start and end pitches across 11 morphable waveforms, shared by both voices.1130

Jacks 8 (6 in / 2 out)

NameSignalVoltageDescription
Inputs (6)
AcctriggerAccent input that further emphasises or de-emphasises the hit; doubles release time for voice 1 and halves it for voice 2.1130
ChoketriggerImmediately stops voice 1 audio when a trigger is received; does not affect voice 2.1130
Ext InaudioExternal audio mix input routed through the tilt EQ section on voice 1's output path.1130
Trig 1trigger≥3VTrigger input for voice 1; normalised to Trig 2 so it fires both voices when Trig 2 is unpatched.1130
Trig 2triggerTrigger input for voice 2; when unpatched, receives Trig 1 via normalisation.1130
V/OctcvAdds a base pitch offset to both start and end sweep frequencies; tracks approximately 5 octaves.1130
Outputs (2)
Out 1audioAudio output for voice 1, passed through the voltage-controlled analog tilt EQ section.1130
Out 2audioAudio output for voice 2, passed through the digital wavefolder section.1130

Parameters 8

NameTypeRangeBehavior
EndknobSets the end frequency of the pitch sweep; inactive when sweep is disabled (Rate fully CCW).1130
EQknobAnalog tilt EQ applied to voice 1 output; CCW emphasises high frequencies, CW emphasises low frequencies.1130
Zones
High Emphasis
Low Emphasis
  • High Emphasis -100–0%CCW half of travel emphasises high frequencies on the voice 1 output.1130
  • Low Emphasis 0–100%CW half of travel emphasises low frequencies on the voice 1 output.1130
FoldknobControls the amount of digital wavefolding applied to voice 2; from no folding at CCW to increasing brightness, harmonics, and noise at CW.1130
Zones
No Folding
Folded
  • No Folding -100–-100%Fully CCW produces no wavefolding on voice 2.1130
  • Folded -99–100%Increasing CW rotation adds progressively more brightness, harmonics, and eventually noise to voice 2 via digital wavefolding.1130
RateknobSets the rate of pitch sweep travel between start and end frequencies; when fully CCW, pitch sweep is disabled and oscillator runs at a fixed frequency.1130
Releaseknob2ms – 14000msControls the release time of the exponential volume envelope shared by both voices; accent input doubles this time for voice 1 and halves it for voice 2.1130
StartknobSets the start frequency of the pitch sweep; when sweep is disabled (Rate fully CCW), acts as a fixed pitch offset.1130
SurfaceknobWhen turned from CCW: first adds a resonant click attack that becomes sharper and quieter as it rises; past the midpoint it transitions to a slow volume attack envelope; fully CCW has no effect.1130
Zones
No effect
Click Attack
Slow Attack
  • No effect -100–-100%Fully CCW position; surface control has no effect on the sound.1130
  • Click Attack -99–0%Adds a resonant click attack at the start of the sound; as the knob rises the click becomes sharper and quieter.1130
  • Slow Attack 0–100%Past the midpoint, the control acts as a slow volume attack envelope rather than a click.1130
WaveknobMorphs the wavetable source for both voices across 11 waveforms: noise, sine, tri, saw, pulse, voice, bell1, bell2, cymbal, spectra, and buzz.1130
