DLP Gets More Oscillators

I've added two sub oscillators under OSC1 and added an independent 2nd Oscillator limited to just saw and square (with PWM). OSC2 can be tied to the CV of OSC1 or controlled independently.

A new sample at the end of the audio section here.

A simple tech track featuring OSC1 modulated by OSC2 here.

DLP Gets ADSR x 2

I have added two ADSR envelope generators to the DLP synth. A couple envelopes go a long way! The envelope was based off a design using a 555 timer from René Schmitz

Here are some audio samples of the two envelopes modulating various parts of the DLP:
VCA and EXP FM running through Distortion (6 minutes of kicks)

More DLP Audio

Here are links to the audio samples and images from the initial build phase of the DLP synth from October 2012:

I finally had some time to turn back to the Dirty 'Lil Penguin (DLP) semi-modular project. A low pass VCF and VCA have been added, so the damn thing is now playable!

Audio sample here.

The sample is straight audio right from the DLP, driven by the FR-777 sequencer, and recorded via Ardour 3 on Fedora. Yes, I may be moving away from Cubase to Ardour as it can run it on a 64 bit OS and it still has drivers for the Emagic Unitor AMT-8!

Additionally I have updated the DLP github project with the latest schematics and code. Next build phase will be the dual ASDR envelopes, and then finish off the sub osc's and OSC2.

Here are some pics:
