I started by building a basic synth voice e.g vco vcf vca env lfo,and expanded from that.
You have no way to sequence notes with what you just posted,consider a midi to cv and maybe switch out the trigger riot for a z8000 or a René.
Also what blender said an output is needed and what exper said still too many triggers
Build up a basic system slowly and get a feel for how things work together and avoid disappointment
If you have an iPad try zMors modular app it may help and doesn't cost the earth (like what you have planned)
