Arturia have just released the v4.0 firmware for the Microfreak and, along with some nice "quality of life" tweaks, the headline feature is the new "WaveUser" oscillator type, which allow you to import your own wavetables!
In this video I walk through the new features, explain what a wavetable is, how you import them and how you can make a perfect wavetable for the Microfreak with nothing more than a sound editor or DAW.
Clarification: on the point of the number of samples per cycle - this is what the Midi Control Centre expects as an audio import format - not what appears to be ultimately stored on the Microfreak (which is 256 samples per cycle). From the perspective of generating your own wavetables from audio files, this isn't particularly relevant, but it's interesting to note that your audio is internally resampled before it goes to the Microfreak.
