Real time audio-to-midi on Mac OS 9?
« on: January 30, 2025, 10:40:53 AM »

Hi all!

Is there a program to do real time audio-to-midi conversion application on Mac OS 9?

Doubtful. Studio Vision Pro does it but not real-time. I remember when it was released it was a gee whiz-bang then.

melodyne right?

MIDI export of your melodies

You can save the melodies detected by Melodyne as MIDI files to view them as a score in a notation program, or you can export your melodies with their pitch and amplitude information to make your favorite synthesizer play the melody with your vocal line phrasing.

Technical data & System requirements

Melodyne is a stand alone application and supports ASIO2. It is available for Macintosh, requires Mac OS 9 or X and 128 MB RAM (256 or more recommended). Melodyne runs on the following computers: Power Mac G4, PowerBook G4, Power Macintosh G3 (blue & white), PowerBook G3 (Wallstreet, Pismo), iMac, iBook. It supports many audio formats (WAV, AIFF, SD2, SND, AU) and in it's second release Melodyne will include both a VST2 and a MAS plugin which synchronizes the application to common sequencer and harddisk recording programs. The Windows version is planned to be available in early 2002.

thinking about it, now i really want melodyne v1 for it to run on my 1994 PowerMac 8100/500 :D

Yeah, thank you guys for the hints. But neither SVP nor Melodyne seem to do REAL time audio-to-midi. They can concert audio to midi, yes, but not in realtime.

You can make pitch estimation patches that output to MIDI with Max, PD, or SuperCollider.
Two libraries that can do very sophisticated pitch following are Tartini and FluCoMa.

I'm pretty sure I said that…

Thank you for mentioning these apps. Are you familiar running them on Mac OS 9? I have done some little things with Max in the past but never anything with PD or SuperCollider. Are the two libraries Tartini and FluCoMa running on all three apps?

I think FluCoMa does have versions for all three, but it is relatively new and written for SC3 which is post-OS9. There is a SC 3.0 beta for OS9, but it was really a late development of SC2.
The libraries may also have dependencies on newer versions of Max and PD.
But basic pitch following is in these apps since their beginnings: it's one of the chapters in the SuperCollider book that was written for SC1.

Thank you for pointing these things out. - I can't find any Beta 3.0 version of SC. Wouldn't mind some links.  8)

there is that pitch to midi VST from dragan,

VST/polyfractus/p2m demo

but it was commercial and we do not have a serial. probably sold like 30 copies. its pitch tracking is rudimentary, has no input filters, and of course it is monophonic.

if you do not want the midi for a certain hardware but only replace a sound against some other (sample based), you might also want to look into antares kantos. it is much better in the analysis, but not so easy to use.

for acoustic instruments as input always utilize autotune and a flexible bandpassfilter for preprocessing. all of the oldschool pitch and transients tracking algorithms are very sensitive to subbass.

Try perhaps kindly requesting siddhartha from Macintosh Garden in his guestbook page if he could look into cracking it. He often cracked many things others requested, very generously. All abandonware like this, of course.

you can roll some pitch tracker using zerox/halfwave methods - and of course [fiddle~] - but it often remains unsatisfying. for proper results you have to add so many preprocessing and hence so many user parameters that you don´t want to give this to an average user.
