Hi!
I´ve started experimenting on the TapeSequencer idea I posted In the Keyboards and Synths page a while ago.
The basic operation would be a LED as the light source for a photoresistor. Since the job of the LDR would be
to work as an ON/OFF switch (not to trigger glitches or bends) for the output of audio (propably the line outs of keyboards), I got to thinking about the sensitivity and speed of the LDR´s, and what kind of currents can be controlled with them..
Could anyone give me suggestions as to what type of LED/LDR combinations would work for this kind of purpose?
The brightness of the LED´s can be controlled, but how about the bahaviour of the LDR´s?
I would like to have a selection of different "enevelopes" for the trigger, i.e. slower/faster LDRS.. possible?
After some fiddling around with C-casettets, I decided to use VHS tapes for they have room for several LEDs and have a wider tape. The initial tests we´re promising and now Im off to get a cheap videoplayer and see if I can strip it into a more convenient size, and add a tape speed control. :)
