Convincing how? As a moog clone? Maybe not, but thats not really what I’m after. I’ll admit that the standard old school vintage-moog-like modules are “ok” but some of dotcom’s "++/specialty"modules are actually pretty great.
The LFO++ is awesome. Has its own envelope and vca for controlling speed and/or amplitude. Very useful on standard lfo duty. Full range pitch tracking too, so it’s basically a synth voice if you need it.
The envelope++ is super flexible: modes for a standard+inverted output, dual AD envelopes, or a4 step sequencer complete with semitone quantizer. It can also be looped.
Gate Math is great as well. Drum patterns, clock divisions, clock multiples, random gates, etc.
I like the SV Filter but seeing as I use the LPF the most, I’d probably opt for something else if I were to do it again. I’ve had plenty of moog style filters (and still have my MF-101), so I’d probably go with an STG Soundlabs Sea Devils filter (EMS Synthi style 3-pole filter). Sounds gnarly. His Post Lawsuit has a nice sound too. His sequential switch is also the nicest looking sequential switch I’ve seen in MU.
I will admit Corsynth has been coming out with cool, unique stuff like their various envelope designs and the lofi machine. Their new drum modules seem fun too. Even their Assistants utility is pretty useful. Usually converting bipolar to unipolar takes a bit more work, like applying an offset and then attenuation, so having it in a simple in/out is nice.
Synthetic Soundlabs has some interesting offerings as well, like the seqwencer. And good solid utilities too, like their 1 MU octal vca or quad lfo. Also a 2 MU step sequencer.
Finally, Lower West Side Studios. They make a ton of open source projects. Lots of CGS and Serge designs. Loads of cool modules. Willing to do custom work for relatively cheap.
