I'm running Syntronik on my M1 Mac Mini with a MOTU M4 audio interface.
The default/usual configuration of "Tape Echo" typically causes low-level distortion in sustained notes or notes played with high velocity. The distortion disappears if I lower the input level from the noon to 10 o'clock or so in Tape Echo. The Digital Delay doesn't have this probelm at all. So, it seems that Tape Echo can properly handle only low input signal. I've noticed this issue in many presets.
Any comments are welcomed.
