Re: YM2612 & distorted sound output

@ TmEE co.(TM) - what do you mean by 'proper' filtering? I've tried low-pass filters at various cut off frequencies, and I can get the envelope very similar to the VST version, but it sounds nothing like the VST. If I take the LPF much below 16kHz or so it starts to 'hollow out' envelope. When I zoo...

This is for channel 1. All the other channels have the equivalent register set to 0. VST - envelope https://img...

Hi, Does anyone have any experience to share regarding the output waveforms of the YM2612/YM3438 ? I've built a hardware synth based around this chip and I'm seeing unexpected distortion on the audio output, even with nothing (other than a scope) attached. For example, I've turned everything 'off' e...
