Is there footage anywhere of the live setup you described (with the Kastle and circuit bent instruments?) - it sounds incredible!

I have a Kastle, it’s a great little device. Have thought about getting a Synapsis in the past, this discussion makes me think I should make the leap! It’s passive isn’t it? I assume it could be used for other mini patch cable devices (like a volca modular) too as long as you kept an eye on the voltages?

#18

looking at that drum code, they converted a bunch of samples to wavetables, but those .h files are all commented out except #include “TR_HH_AT.h”, and that one actually has 4 samples in it. The problem is I don’t see those referenced anywhere in the main code.
So this leads me to believe that the drum firmware does not use samples as wavetables.
For that we should be looking at kastleSampler instead. Anyone try this?


However I do see references to decay envelopes in the kastledrum code so maybe it is actually synthesizing the drums?

check https://github.com/bastl-instruments/kastle/tree/master/kastleDrum/bastlAttinySamples maybe these are the samples he meant

way out of my depth but this sounds like pulse code modulation or PCM of casio-pk fame a sample-based pseudo-fm converted to digital [1s & 0s] coincidentally pcm had enough processing power to spare for vibrato/delay on some instrument presents sort of like a decay envelope

thank you! ptzero.org/kate-finley support the netlabel!!

synapsis is totally passive yes, should be fine w volca modular +/-3.3v since attiny85 range 2.7-5.5v

Well apparently there’s a revision of the Kastle 1.5 without swappable ATtiny chips. Unlike either the 1.5 or 1.5b, there appears to be an undocumented revision (my board says Kastle SMT v1.7.1) with different, smaller chips, soldered to the board. ¯_(ツ)_/¯

#23

Update: looks like it’s using surface mount ATtiny chips (hence the SMT in the board revision number). There are through hole points on the board that are labeled +5v, MOSI, GND, MISO, SCK, RES, which directly correspond to programming points on the ATtiny.

So I may still be able to reprogram using some jumpers.

Update: it’s alive! I was able to install kastledrum and kastledrum_lfo_clk. Hopefully they’re on the right chips (LFO on the left). I am getting drum-like sounds but it’s very fussy.

WHAT

is must update, i see new noise sources +16step sequencer done sold @ryanruppe can confirm?

#27

I don’t think the step sequencer is new. The original Kastle had a “stepped voltage generator with random, 8 step and 16 step loop mode” but the steps were sourced from the random source.

kudos!

corrected yes 3-bit rungler dealie indead does 16-steps

I like your description better.

" It means that when BIT IN [now FEED] is not connected the STEPPED [now PATTERN] output generates a 16 step pattern. When it is low it generates an 8 step pattern. When it is high it keeps generating a random pattern and when it is altering it generates a semi-random pattern."

@ryanruppe hi, so you just used those pins there? how hard it is to do this? I have Arduino Uno, so i will just buy board, some capacitators and its ready to go?

#33

Sorry if this too stupid/obvious, but will it connect to eurorack, like clocking it from a eurorack?

Obviously one needs “some special cable” but thinking more about on the electrical level…

#34

@a773 there is I/O jack port which can be then accessed via patchbay

#35

Great, thanks! Seems like an ultra cool device!
