Depending on what I use for the input, the problem gets worse. For example, using Plaits Shades to produce a constant voltage, I get fluctuations from 0 to about +20 millivolts. Using a 4MS SMR in volt/oct mode, the values fluctuate ±50mvs. As a sanity check, I plugged both of these directly into an oscillator’s v/oct tracking and there were no such fluctuations in the pitch.
I’ve been using this script to debug the issue, triggered by the metronome beating at 500ms
DEL 100: P 0 A - delay here as I read there is some latency when reading from
In a test with constant output from Shades saw the values set in the pattern toggle irregularly between
5648 (strangely here no other values were read). Values from the SMR ranged from
3387 with many other values in between…
I was able to test the teletype & SMR combo each in a different case, in case it was somehow due to the power supply, but still had this issue.
My teletype is running firmware 3.1. Has anyone else seen this issue/can explain what might be going on/possibly have a workaround? I bought my module second hand a few months ago, hoping that it’s not in need of repair
