Ultram

The Ultram VST plugin was developed to be a simple audio to midi convertor. It converts the amplitude of audio to a midi event such as a note-on, cc message, pitch bend, channel aftertouch or program change message.
It has a single-pole lowpass filter with controllable attack and decay, a note filter, and it can send the midi messages to the VST host (if supported by the host) or an external hardware device setup in realtime using VST parameters. It also features a LFO generator with different shapes including a random noise generator.
Ultram can also be controlled by MIDI: note on MIDI channel 1 controls the LFO frequency, note-on velocity controls LFO amplitude, note-on and note-offs on other channels set note filter to allow and block, and CC messages control VST parameter with the appropriate number.System requirementsVST Host
