Muff's Modules & More

First post here so apologies for any newby-isms. I'm very excited by this VCDO and the possibility of building a rock-solid, easy-to-setup synth around Druid chips

So, I'm wondering, now that the great Tom Wiltshire has conceived solutions for the VCO, Noise Source, and all the modulation generators needed in a typical synth, that only leaves VCA and VCF. If one were building an all-Wiltshire-sizer:
- would it be best to adhere to Tom's 0-5volt CV standard throughout?
- what would be the best VCA & VCF to use?

Well, the wavetable nature of the VCDO means that you can have so much fun without needing to route through a VCF. I've been modulating the wavetable with the bipolar output of my Recycler, together with my Modulation Druid - very animated sounds, and a whole new ball game compared to the usual VCO > VCF > VCA signal path.

This week Tom sent me the latest version PIC, which includes a really funky new feature. The 16 sub osc waveforms are arranged in four group of four waveforms. -2oct, -1oct, unison, +1 oct. So, you can drive the subosc waveform select CV input with an ADSR or LFO to create octaved arpeggios! Such a cool feature.

I've also tried the subosc as an LFO at the VCDO's lowest range. While it does not go slow enough for really slow sweeps, it is comfortably sub-audio and can be pressed into service for fast LFO type duties.

Sounds great, what a cool idea with the sub octaves!!

Any news about those artifacts mentioned earlier in the thread, are they present in your prototypes too?

A few soundclips, I'll be doing more later this evening.

First up, I've got 2 x Waveriders built now, so I'm using my Kenton Pro 4 to use them both as a duo-synth. So this is 2 x Waveriders into 2 x Roland VCAs, controlled by 2 x Recyclers:

Some douphonic Kometenmelodie:

This next soundclip uses an LFO (a Modulation Druid) to cycle through the sub-oscillator's octaved waveforms. Just to make it clear, there is no arpeggiator or sequencer being used - all live action:

Next up, using both LFO and ADSR to modulate the main wavetable:

More to come later, expect to see soundclips of a bunch of my various projects tonight.

oh fucking YES! hihi

and the artefacts seems to be a thing of the past? was that a bug?

WOW, sounds great!!!

WoW!

right i absolutely want three of these asap please
This is fun!

tom, i did not read up the whole thread. oops

will there be some documentation uploaded in near future? right now i am actually using only the x4046 VCO by thomas henry, and i would love to build a couple of DCOs if they are PIC based (and that's how i understood it?).

A couple more clips. This time featuring just the suboscillators - their waveforms are more conventional than the main VCDO output, and lend themselves to some subtractive synthesis.

So here's 2 x Waverider sub oscillators through my Roland 100M 24dB/oct lowpass VCF clone:

...and here's 2 x Waverider subs through my Multimode in HPF mode:

http://www.frequencycentral.co.uk/wp-content/uploads/2012/07/Waverider -Subs-HPF.mp3

This one feature 2 x Waverider subs through different VCFs, with an LFO modulating the waveform/octave of one Waverider to create a pseudo-sequence - no sequencers or arpeggiators were used.

cool, so who's doing a pcb run? (it's been a long day and my brain aches!)
