Having tons of fun with this software. In short, it’s a wavetable-maker with some very neat functionality. I haven’t been much into wavetables before, but it’s really going to change. The software is free, and is made to look vintage on purpose: after all it’s been inspired by PPG Waveterm hardware computer from early 1980s, used for wavetables creation specifically for PPG Wave 2.2 synths.

Although Audioterm by Matthias Gurk can only output a bouquet of up to 33 single-cycle wavetables, there are tons of neat functions that may give you some extremely unpredictable sounds that can be then refined to very unusual but also beautiful timbres. Surely take a look. It can output wavetables in multiple formats, so if you have a synth that can load custom wavetables at all (among the freeware ones – WhispAir and Surge XT can do it), this software may become your beautiful friend.

There are other freeware wavetable-makers out there, however, and I’m going to study them too.

P.S. It’s a shame that Native Instruments Massive (the classic one, not X) can’t take in custom wavetables, though.
