I love TE's stuff and I've always thought it was a huge miss that they don't opensource everything.
The new OP-1 looks great and so does the TX-6, but I'm not buying either knowing that I can't maintain/upgrade/contribute.
Will I pay $1200 for a 6-channel mixer with dsp effects? No.
Would I "sponsor" the same exact mixer if it was open hardware/software and hackable? Absolutely, because that should exist in the world.
Same with the M8 (which appears inspired by TE and LSDJ): https://dirtywave.com/products/m8-tracker
Glad to see more open source music hardware happening.
Maybe we're at the beginning of a new DIY wave.
