Moog Dfam

Drummer From Another Mother (2018)

Moog Dfam

"A semi modular a percussion-focussed analogue synthesizer, with a built‑in step sequencer.  "


HISTORY Originally a DIY prototype version during the 2017 moogfest, then released the year after designed to compliment the Mother32 synthesizer with different outfit, total black, leaving the silver line.

Other Moog DIY:
- Werstatt (never released)
- Bfam (never released)
- Subharmonicon 
- Spectravox (never released)

Below a picture of the original 2017 edition:

Overview basically it keeps the same mother32 desktop case that can be mounted into eurorack modular system (where it occupies 60hp). It's not really a drum machine, but more a drum synthesizer with handy 8x2 sequencer.

Terminal connectors:  24 patch bay front connectors with 1V/Oct Cv type, but it's already routed to generate sound without patching cables. 
PATCHBAY OUT: VCA Out, VCA EG Out, VCF EG Out, VCO1 Out, VCO 2 OUT, Sequencer Trigger Out, Sequencer Velocity Out, Sequencer Pitch Out.
PATCHBAY IN:  Trigger Input, VCA CV In, Velocity In, VCA Decay Control In, External Audio In, VCF Decay Control In, Noise Level In, VCO Decay In, VCF Mod In, VCO 1 CV In, 1-2 FM AMT In, FCO 2 CV In, Tempo Control In, Run/Stop, Advance Clock.

On the rear side:
- audio out jack
- 12VDC with positive center 230mA draw
- kensigton stuff (what the hell is that...)
As strange as it seems, there' s NO Midi.

VCO  two  oscillators VCO1  /  VCO2 + a white noise generator for inharmonic frequency
The VCOs are identical, featuring wide octave range (10-octave range from manual) and 2 shapes (triangle and pulse) , they can be indipendent, tuned individually and modulated by Modulation frequency. If not enough of metallic sound, the VCOs can be hardsynched  in "VCO2 > VCO1 phase" manner. Finally the Mixier controls level for Oscillator 1, Oscillator 2 and White Noise/External Audio Input 

Envelope 3 bipolar EGS hard-wired for VCO pitch, VCF filter and VCA.

Filter analog LPF and HPF with resonance and pure self-oscillation.

Sequencer very easy (easier than mother32) step sequencer composed by 2 rows of 8 steps: first one is for the pitch, while second one is for velocity. It has internal clock with high rate, or can be clocked to external analog clock (step in).
