Thans for making these videos. I greatly appreciate your point of view and your music.

[@synthpro]

Thank you very much, glad you enjoy my videos and music. Thanks again.

[@pablowentscobar]

Really interesting video. Cool synth, thanks for going through it so thoroughly. I really love these types of video where we get to see everything. Good stuff.

[@synthpro]

Thanks for watching. It really is a interesting and unique synth for sure.

[@IvanEngler]

awesomeness

[@vlzmusik]

The 3350 filters are state variable filters, so that's a complete different design. Each is a two-pole filter capable of lp, hp, bp, br and ap, depending on how they are wired.

[@synthpro]

@@vlzmusik you are correct. I meant to mention that but totally forgot. It basically has two state variable filters for what they call upper and lower and then one is switchable to off making it a single low pass filter.

[@vlzmusik]

yes, I really like this design, with 2 filters there's so much flexibility. Reminds me what they do in the elka synthex and also oberheim matrix with the reconfiguration of filter poles. Very nice.

[@brettlemmings]

thank you for excellent demo of this, i really want one now !

[@synthpro]

@@brettlemmings you're welcome, it was a fun synth to work with. Thanks for watching.

[@0richbike]

Fascinating bit of kit. You watching this Cherry Audio?

[@lesingemonotone]

The A and D envelope pots seem to be logarithmic according to the service manual, maybe that can explain the strange envelope behaviour?

[@synthpro]

@@lesingemonotone I'm sure that's what it is.

[@oldbladderhorn]

sure does centre tap and italian and note note note center tap note note italian it into a very deep reverb and panned all over the spectrum

[@nonsuch]

Sounds decent. It's really a shame about the ADSRs. Bad design but, not hopeless. It's fine for the museum however, If I owned it I would change some component values to dial it in proper. The Decay is the most unacceptable. Cheers!

[@synthpro]

@@nonsuch I agree, if it were mine or going to a player, I would change some things for sure. I believe they were trying to avoid a direct copy of moogs EGs but kinda missed the mark a bit.
