Latcher is a noisebox synth in the same vein as NANDroid and XORbot, and contains many of the same features as those previous synths. The sound-generating part is something of a cross between my Modutronic Messmaker circuit and an Atari Punk Console, in that it combines the AM/FM oscillator configuration with the osc-triggered monostable of the APC. In keeping with the logic-based theme of the previous two noiseboxes, it also includes a switchable “mod osc” that is fed into an XOR gate with the AM/FM signal on the other input (pre monostable).
Here’s a little audio demo:
