Hi, this instrument i made convert monophonic audio sources to pitch/gate and MIDI, but the MIDI still had lots of problems. It is based on Frequency Tracker Instrument from library and i've customized it to receive signal from my electric guitar. Anyone kind enough to give it a try and tell me your opinion ?

The Instrument is now moved to the bottom of this page.

Hi, this is my latest update for Elektro Guitar. MIDI Out is now functioning but no pitchbend yet. Lots of stuff added. I also add a screenshot.

Thanks W.T. , hope you enjoy it as much as i do.
Fix some problems when changing control rate to other than 400 hz, and a lot better MIDI Out, although still not complete (no retrigger, PBend). I guess i just take a break for a while... coding MIDI is so frustrating.

Whew, finally i got my ins the way i wanted it. Everything's been working quite well and very playable, so i guess i could start my music project that has been left out since i started building my ins.

Some ideas from trying out several synths that i put on this version. Also i've tried with vocals and it works quite well. And i guess this is the final version of my ins.

Another try in building audio to MIDI converter.. i got the idea for this one from hearing guitarist talk about their hardware guitar synth, that they can play drums on low E string, bass on A string, trumpet on D string, and so on. It makes me wonder if i could build a MIDI converter that could function like their hardware stuff did.

Beside that, i also want to try the method of using static resonators, unlike my prev ins that based on Frequency Tracker Ins' moving resonator. This method results in very accurate pitch tracking that there's almost no glitches at all, which i think that will simplify the MIDI function to 'understand' the pitch data, because the pitch from audio input is sort - of - quantized by the resonators.

On the downside though, the pitch from audio input has to be almost perfectly in tune to be recognized by the resonators, and the 'infamous' audio to MIDI latency also occurs in the conversion.

Maybe anyone knows other method/technique for tracking pitch ?

This one's just like Elektro Guitar, but customized for vocals or speech (just like the original Freq Tracker Ins), with an input signal amplitude to free-form envelope converter added.

This has major changes since v1.17, so i guess that version is not final yet...Smile . And because of that, i think i'll keep the 1.17 version posted.
Added some fun stuff and more tweaking accessibility, now it is more than just a pitch/gate converter, it can be used as an effect to generate trigger or random pitches from other sources beside electric guitar and vocal (try drum loops).

This one is actually consist of two ins. First one is sort of audio to 'MIDI Keyboard' converter and the second is some simple additive sine organ and a drum loops to organ converter that its fundamental pitch can be played via MIDI.

This is a tribute to Freq-Tracker Ins which i really loved. Now i've added MIDI capability that can be used to control another Reaktor Ins via internal MIDI connections or external device via MIDI Out.

Have fun using it, feel free to change/use anything.

Another monophonic pitch to MIDI converter, in this one i try different approach on 'translating' the detected pitch into MIDI data (note on/off, pitchbend, velocity). And because it transmits MIDI signal, it can be used to control external synth like VSTi or recorded in a sequencer.

A polyphonic pitch to MIDI converter, it's quite stable now compared to the previous version.

A voice-controlled synth, doesn't have MIDI option but has a quite low latency. This one uses a different method from the previous Freq-Tracker based ones, and has an 'intelligent' harmony generator.
