Jim,
TTS has very solid interface. The only thing is "missing" is importing of user SF2 Banks. If it had that, it would be a dream come true GM synth :) TTS as it is, probably has only 100-200meg sound bank (at least it sounds like that). I would like to use high quality 5-10GB GM compatible SF2 banks.
Chrordpulse... I was a fan of that too once. Good tool to get idea flow. Probably most of people never heard of it here... For those who do not know what it is.... It is a super fun sequencer / style player (actually much more than that). Very clean design and simple to the bone to use. Biggest issue is that it only uses "in house" styles and it is a standalone, not VST
Something like Chordpulse sequencer would also be great if integrated into Cakewalk, but I guess not for 2018 update release :)
