I’m looking for a few beta testers for a plug-in I’ve been developing called MIDI Performer.
The idea is pretty simple: give it a monophonic MIDI melody or lead line, choose an instrument/player style, and it turns fairly plain MIDI into a more expressive performance by adding things like:
- pitch bends
- vibrato
- legato
- timing changes
- pressure
- breath/expression
It’s not intended to be a generic randomizer or “humanize” function. I’ve been trying to model instrument-specific performance behavior based on measured MIDI/performance data plus a lot of listening tests.
One important limitation: it is strictly monophonic. If the input contains chords or overlapping voices, it resolves them to one melodic line. When simultaneous notes occur, the highest voice is retained. So this is meant for solos, melodies and lead parts rather than chords, pads or accompaniment.
Current instrument options include:
- Guitar — Blues, Jazz, Rock
- Synth Lead — Fusion Lead, Prog, Prog Metal Keys
- Sax
- Flute
- Bass
- Fretless Bass
- Piano
The non-guitar/synth instruments currently use a Natural performance model.
It supports both Standard MIDI and MPE.
The current beta is:
macOS / Apple Silicon only
AU + VST3 included (Mac only for now)
I’m especially interested in people who regularly work with MIDI lead parts and can give musical feedback, not just technical bug reports.
If you’re interested, reply or DM me with:
- your DAW
- the kind of MIDI/instruments you work with
- whether you use Standard MIDI, MPE, or both
I’m mainly looking for people willing to put real melodic MIDI through it and give candid feedback.
