Hi Folks,

The Blacet ID2510 (fancy noise source) has a lot of blocks in its block diagram. These simple mods give you a little more access. The usual disclaimers apply: don't get in over your head, forget about your warranty, etc. Also, I made mine with banana plugs so where I've added a jack and a switch you would probably use a switching mini-jack. I used very stubby switches so they don't crowd the knobs.

#1 There's a multi-mode filter with a switch that lets you select band pass or low passed noise as an input to a sample and hold. The output of the S&H feeds a quantizer and both outputs are available at the panel. Mod #1 lets you feed the S&H / quantizer with an external signal.

Add the jack & SPDT switch. Wire the jack to one side of the new switch. Take the wire off the center lug of the existing switch (Filter LP/BP) and move it to the center lug of the new switch. Run a new wire between the two remaining switch lugs.

#2 That quantizer is a nice piece of work. Good Mister Blacet even provided a choice of four scales using a little trim pot on the PCB. This mod simply remotes it to the front panel.

Remove RT2. Install a 50K linear pot on the panel. Hook up the three wires. Piece-o-cake.

#3 This one doesn't really count. A choice of internal or external S&H clock is a standard feature accomplished with a switching jack. When I bananafied this module I needed to add a switch.

That's enough for me but if you like drilling holes I suppose it wouldn't be too hard to provide patch points for the in and out of the filter.

Enjoy!

i'll second that; my minimally invasive version loses the clock-CV input and uses that panel hole to mount the pot. i can still patch in an external clock and CV that if needed.

sweet module.
