PolAr Tools

PolAr Synthesizer + PolAr Tools

As a long time user of Native Instruments Reaktor, I had time to discover some of the “not so known” tools kindly offered through the package, through gifts from Native Instruments, through the amazing User Library and even through the forum sometimes.

At the very beginning of Reaktor 5, the offered ensembles, instruments and macros library was obviously different from today, even more since the introduction of the “Blocks” framework.

I always kept under hands and used often 4 simple tools that I didn’t created but modified slightly, mainly the appearance, to fit with my needs and the aesthetic of “PolAr” synthesizer.

Amp to CC

Audio signal amplitude (level) to MIDI Control Change message converter using envelope follower.

Audio To MIDI

Realtime Monophonic Pitch to MIDI converter using AMDF (a variation of AutoCorrelation), a method that subtracts the audio with delayed version of itself to find periodicity (similar repetitions) of the audio waveform, and Zero-Crossing method for PitchBend measurement.

Graphic EQ 32

32-band graphical EQ. The interval between two neighbouring bands is one third octave (4 semitones).

Samp Env To CC

Audio signal amplitude (level) to MIDI Control Change message converter using envelope follower.

As you can read, Amp To CC and Samp Env To CC basically does the same thing but Amp To CC is useful if I want to control “PolAr” from live audio input like a live musician, even a singer or by “PolAr” itself. Where Env To CC will allow me to control “PolAr” by reading a waveform, why not especially designed to obtain some nice/desired changes?

Graphic EQ 32 might not be the best tool to sculpt sounds but… I don’t know why, I find myself using it regularly and obtained some unexpected sonic changes on some precise sounds or samples. On winds or air movements made with “PolAr” this EQ can really make the difference on the final sound and its credibility in reproducing sounds it was made for.

Audio To MIDI, if far away from the complexity of what Ableton Live can do with the same function but, it’s a tool on it’s own and I managed to play drums on my desk with a close microphone and this tool generated most of the MIDI notes. Feeding it with a sample of mine, generated some wrong MIDI notes, replayed them with the same sample as a source, obtained nice sounding random audio artefacts.

I hope to modify some more tools, to make sure every tools are working well for their own mission and the idea to create some ensembles combining the various functions of compatible tools is running around.

PolAr Synthesizer next evolutions:

1- To finalize the set of tools.

2- To rework “PolAr’ TouchOSC interface or create a set of dedicated templates to control various tools.

3- To enter the world of 3D audio through AMBEO set of plugins (I dream about their AMBEO microphone “VR Mic”) or some other Ambisonics solutions and using “PolAr” along some especially created and recorded music.

I definitely want to go deep with this project since it is something I need and use but at top of all, I created it from nothing, listening to Mathieu, excellent professor in synthesis, learning from him and finally obtained such a result that I feel fully involved to maintain it as a professional, technologically advanced and ever evolving sound design tool.

Nerdy times ahead 🙂
