VSTForx allows free routing of VSTs, so it’s kind of “modular” VST host.
- add plug parameter on stage and bind them.
- operators for parameter connection (inverse, EXP, …)
- step sequencers and
- audio2parameter-value modules(e.g. ADSR-trigger)
- load several VST-instruments and assign them via MIDI-channel
- comes as fx, and VSTi
Currently available for Windows. Mac version planned.
