Texas Instruments TMS3615 Octave Multiple Tone Synthesizer (2 footages)

 

tms36152 footages ( 16', 8', or 8', 4' or 4', 2')
Sustain of the output signals is possible by simply connecting a capacitor (1 uF) to each key input
Sustain decay time adjustable from a few ms to a very long time (key memorization) by connecting a variable voltage to the appropriate terminal
Possibility of controlling the amplitude swing of the footage outputs, to minimize the spread among different devices, by connecting a simple external network to the appropriate terminal.
Asynchronous reset to synchronize devices of different ocataves.
Single power supply 15v or 12v typical.
Clock output for lower ocatave device
