I would actually like to see some more exotic effects to be honest like reverse delays, harmonizer, and maybe just maybe...a vocoder.
Me too... but for some reason it seems that the way FX are made on DSI synths they can only hold a certain number of them... Sequential never explained why this is, but if you look at all the synths with their current FX engine, none have had any additional FX added, even if this is something most users have requested... so this is a department that Sequential could certainly better themselves at because compared to other newer synths like ONE, PEAK, DM12, QUANTUM, Minilogue XD etc. the Sequential FX engine is really lacking behind.
They would need to make more FX slots, and also let the user decide the routing of them. They would also need to make the FX slots available at the same time in these configurations... all the above synths i mentioned have this. Also they should include more parameters, not just a measly 2-3... They do not need to make dosens of parameters per FX algorithm, but definitely more than 2-3, especially on the delay and reverb algorithms. Also, the reverb algorithms should have some way of modulating the signal... reverb modulation is key to getting really lush and dense sounding reverbs... Currently (on the REV2) I have to fake this by using a second layer with FX mix set to "100% wet" and copying the other layer's sound and putting vibrato on it to get the reverb modulated... it's a waste of half the voices.
so no matter what synth Sequential does, I certainly hope that they will up their FX engine a bit... it's starting to look pale when you compare it to the other synths out there right now that has FX built in... either do it right, or completely remove the FX all together. To me, FX is an integral part of designing a sound/preset, and thus a very impotant aspect of a preset sound. The FX engine many doubles your creative options in sound design, it's the icing on the cake.
And if Dave is not up for the task, or don't want to bother with it, he could team up with a good DSP coder to do it for him... he's worked with others in collaborations before... I'd wish he gave the owner of ValhallaDSP a call, and arranged something with them... they know how to create really good reverbs.
