#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!

#36

Honestly it’s so much easier with that ATtiny programmer, I can’t recommend it enough.

If you have a Kastle 1.5 with removable ATtiny chips, you Mount them in the programmer or on the breadboard, if you have the one with surface Mount chips, I can show you the connections you need to make with jumpers.

thank you, i will check my unit

That video is so helpful

@ryanruppe so have you been able to upload the newest drum firmware to the kastle? and now your kastle works exactly like the bastle drum?

Pretty much, yeah! Kastledrum is essentially kastledrum firmware running on Kastle hardware. Yeah the labels of the patch ports have changed but it’s the same points, knobs, etc.

#42

Hi,IT seems I have those chips hardwired.so will you be able to send me connections to the Arduino?also which wires did you use?thank you very much!

#43

Hi! It’s so much easier with the sparkfun ATTiny programmer, but either way the connection points are the same.

Using jumpers (I used the ones that came with the Kastle!), bridge
Reset (1) to RES
Ground (4) to GND
5V (8) to +5V
Digital 2/Analog 1 SCK (7) to SCK
Digital 1 (PWM) MISO (6) to MISO
Digital 0 (PWM) MOSI (5) to MOSI

And then use the Arduino app to install the firmware. Kastledrum goes on the right, and Kastledrum_clk_lfo goes on the left.
