Are there any simple, free (or cheap?) MIDI sequencers that run as VSTs?
I've been using a thing called Phrazor inside Mulch 1.0. It runs as a VSTi inside Mulch, and is a host itself. So e.g. if I have some VST synth I load it inside Phrazor. All I see in the patcher in Mulch is Phrazor and one pair of outputs for all the instruments.
Since Mulch 2 can do internal midi-routing, there are some clear benefits in switching to a simpler sequencer VSTi that does nothing but send MIDI. The instruments can sit in Mulch's patcher and I can use Mulch's parameter modulation options to make everything go wrong. ;)
