“I just added a few things to my site that may be of interest. One is a very small collection of speakandspell bending schematics, the other is a page loosely explaining how to added a programmable step sequencer to your speakandspell to make a speakandspell drum machine…
The effect is a glitched out sounding, programmable sequence. There are 8 steps in the sequence and each can be turned ON or OFF. As the sequence runs, it advances one step at a time, 1 thru 8, then repeats. When a step is set to the ON position, it activates 2 effects in the Speak&Spell for the duration of that step. The 2 effects are a tone generator and a “hold” effect.
