Pendulum/Ratchet | ||
I always though that my Buchla system would benefit from a dedicated module to generate a bunch of correlated pulses. Sure, you can use sequencers and function generators for this sort of thing, but having a clock source generating a wide variety of pulses of different flavors was very appealing to me, so to that end, I came up with the Pendulum/Ratchet. |
Pendulum section The main clock rate goes from about eight and a half seconds per tick up to 10 ms per tick. |
Transport controls These do the obvious things to the clock. Sync does one non-obvious thing, though. In addition to syncing the clock, it also resets all the divisors. |
|
Pulse Density Modulation With the Density control all the way up, the "tock" output is the same as the "tick" output. Turning Density down creates a pulse train that randomly picks pulses from the clock to send out the tock output. |

Division A and B. These are variable Ratchet Divisors that can be freely positioned from a divisor of one to over a hundred. The divisor values can be limited to some interesting number sets, including primes and the fibonacci series. The limit options are arranged in decreasing density: limit off odd (1 3 5 7..127) even (2 4 6 8..128) primes (2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97 101 103 107 109 113 127) trip (1 2 3 4 6 8 12 16 24 32 48 64 96 128) Fibonacci (1 1 2 3 5 8 13 21 34 55 89 144) ^2 (1, 2, 4, 8, 16..128) |
Ratchet section can be clocked from an independent source, although it will still listen to the sync jack as noted above. Either the tick jack or the tock jack can reach the Ratchet in jack with a shorting plug. Fixed divisors Divisors that include common note values (2s column) and triplet values (3s column). |
