that is/was my (temporary) solution for the slow gui:
a metro at 8 hz sending bangs to a global send
and a [f] receiving these bangs before every slider/number/ which is
updated via midi-ctl, counters, sequencers, whatever.
while directly connecting a few midi-controllers to sliders could easily
stall the gui (when the knobs are moved), this solution looked not very
beautiful, but caused no dramatic cpu-spikes, even without 2d hardware
