Running Teletype version “TELETYPE 3.+ BETA E27F640”
I’m having issues with “chirpy” sounding notes and decided to investigate. I found the Teletype’s onboard CV outputs have 1-4ms of latency (i.e. 3ms of jitter)–4ms is more than enough to cause a “chirp” if it’s pitch CV whose change happens after an envelope trigger.
The following metro script demonstrates the problem for me:
TR.P 1 // triggers the scope
CV 1 V A
TO.CV * 2 V A // optional, gives a nice visual reference with a Telex output, which has virtually no jitter
I’m seeing issues with trigger output duration, too–it might be related. I can post scope images if needed, but the above script should do the trick.
Edit: now I’m seeing 2-6ms after a restart to get the firmware version.
