TTS-1 synthesizer

[happen135]

I'm an old player. In CbB and sonar, I kept the TTS-1 synthesizer (a feeling I couldn't give up). I accidentally found that if the TONE switch was turned on in the audio source editor, the audio source would not have a sound. Turn the MID knob to the left or right, the sound would come out, and turn it to the middle and there would be no sound. What's the reason for that? Who has this audio source? Please help me try it. What I want to know is whether it's a common problem or my personal computer problem. thank you!

I was able to reproduce this with TTS-1. That setting affected all the patches I tried. I doubt that it will ever be fixed because the TTS-1 is no longer a supported product.
