Flame have been around making interesting Eurorack modules for quite a while now, the MÄANDER is I believe their first desktop synthesizer.
MÄANDER is 4-voice polyphonic Wavetable synth and is compatible with wavetables from the 4VOX module. It has unison modes and controls such as Colour and Glide along with twin LFOs and an ADSR envelope. It also has a 12 band filter bank instead of a regular filter... The Filterbank can be sequenced so it can really make for some interesting patches.
