bubbleosund Introduces New Dual ADSR Eurorack Module Based on Roland M-140 & SH-101

"The first demo of bubblesound's dual ADSR. A VCOb and uLFO being sequenced from X0Xbox. The gate is going into the dADSR, the 4ms PEG and the Rotating Clock Divider and Multiplier. 1 VCA4p acting as a mixer for the 2 oscillators, mix out into channel 4 of the VCA, dADSR going into the CV for channel 4, out to the SeM20 and back into a second VCA4p. High Pass out from the SeM20 into the Wow and Flutter which goes into the second VCA. mix out to a speaker. The 4ms modules are doing clock multiplication and division for the FMing and for the gate of the dADSR."

"The dADSR is clone of the Roland M-140 module, and are very similar to those in the SH-101. As a transistor based EG, it's very responsive and snappy. The perfect companion to the VCA4p.

In addition there are 2 LFOs acting as clocks, one for each EG. There are 2 LFO outs per EG, a Triangle and a Square. The LFO operates independently from the Gate, so when using an external Gate to drive the EGs there is still an LFO available. The Inverted Gate outputs are just what they sound like, an inverted version of whatever is coming into the Gate input, either the internal Square wave or an external Gate.

The Output section has the standard 0-8V and inverted outputs of most EGs, but there is also a +-5V out for modules that accept bi-polar modulation like the SeM20. These are also good for FMing VCOs and anything else you
might use an LFO for. The Mix section is simply that; the two normal, inverted and +-5V outs get mixed for more complex envelopes.

With 2 EGs, 2 LFOs with 2 outs each and 9 Envelope outputs this is the most versatile and dense analog EG out there.
