Update 2016-12:

Bought a DW6000 again and mod it to have a mixture of DW6000 and DW8000 waveforms.

Background is that I miss saw, square and sinus from DW8000, but I like DW6000 more because of its chorus.

DW6000 only has 8 waveforms and DW8000 has 16.
So I made a mixture (with an hexeditor) from both machines to replace some of DW8000 waveforms with special ones that are in DW6000.

Update 2024-02-25:

I have in beginning of 2020 stumbled over Mateusz Kolanski waveform mod which adds 64 waveforms to DW6000.

I got his PCB with firmware hack to add a new parameter (14) to be able to change waveform-bank.
