Do you mind sharing a bit about your digital modelling?<br></span><span class="">
Are you modeling the analog circuits using spice like equations?<br>

<br>
Yes, sort of. I can;t go into the details now, but it's like a spice model optimised for speed (realtime calculation on DSP) and audio quality.<span class=""><br>

Seems impressive your model could pick up on these details given even people making clones missed out on those<br>

You can easily see the difference in the rimshot waveform when it is high-pass filtered. There seems to be some discussion about it here (the diagrams are perfect for this discussion although I haven't read the thread...):<br>

The RS waveform looks like the very top waveform when viewed directly at the output of the VCA (before the HPF). (The second thick waveform is just a magnification of a sketch of the RS waveform in the TR-909 service manual.)<br>
<br>
The RS waveform looks like the third waveform down at the output of IC50b (after the HPF.) It is quite an aggressive high-pass filter at about 230 Hz, and it's LF rolloff has the effect of introducing a "tilt" or "droop" on the otherwise "flat" portions of the clipped RS waveform.<span class="HOEnZb"><font color="#888888"><br>
