Muso: I believe your issue is less of "drawing" the waveforms than "generating" the audio into RB. That procedure is much faster now that RealBand is 64-bit for 2021 and now supports SSE2, SSSE3, AVX, and AVX2 processor extensions which together speed up any DSP and generation by 4x - perhaps give it a try again if you have 2021, see if it works better for you.
