If one were to try to replicate the functionality of ism in Pulp Logic tiles (which I think would be the way to go as there are more options) hereās what it might look like:
- Case: Pulp logic doesnāt make a similar case but they do have have boxes and heāll also cut rails for you to size, so might require some DIY on that front if you want the box. Iāve ordered several sets of rails from him and experience is good.
- USB Switch for grids: probably no dice here. You can use the USB tile to give something power but there isnāt a USB -> CV tile.
- 2 channel cv mixer: You could use either one of the three channel slider-based mixers if you can live without cv control, or a collection of VCA tiles, attenuverter tiles, and a sum tile.
- Bus: I personally donāt mind long patch cables but you could use the tether Tile for this or maybe hot rod some passive mults together on the underneath.
- Attenuating inverter: Attenuverter tile is probably even replacement, though I like the att-off tile with dipswitches for more functionality. Both are great though.
- Gate: A combination of NSL-32 VCA and maybe an Att-Off to process the cv signal.
- LFO & Noise: Here weāre not going to get very close. Tile options for noise might be from the RND (stepped random voltage), V-Noise (random pulse generator)+Slew (slewing the pulses), or some combination of those things. LFO we can do better though: Cyclic Skew gives you triangles, saw, shark fin, and everything in between, add a Compare (Comparator) for the square wave version.
- Input: input part is pretty straightforwardāGain tile with a 1/8 to 1/4 adaptor. The gate and envelope follower might be assembled with a slew tile and a Compare (I havenāt tried that before but I have the pieces and might give it a try for fun, I much prefer Pulp Logic Entry Point eurorack module for this sort of thing and even more the RS-35 which also gives me pitch as cv).
- Spring Reverb: Spring Reverb Tile. Has some nice routing so you can process the feedback. Works off tiny cables so if you want RCA youāll have to attach appropriate cables.
- Outputs: Some combination of the Outputs tile (which gives you 1/4 L, R, and headphone out), Mix-A tiles, Sum tiles, or 2180 Tiles with any of the knob Tiles (which send voltage when no cable is in their in holes).
Overall obviously a Pulp Logic Tile system isnāt going to be exact (the pink and white noise would be very much missed), and/or will take up more space. But you might find yourself swapping in other interesting things as well (Breath Controller anyone?). Also goes without saying that it wouldnāt be as pretty. Though I suppose you could order blank aluminum tiles and do your own art. Or even order up your own face plate and remount the tiles to it if youāre super ambitious.
I did this mainly as an exercise to see how close it could get. John Kennedy at PL is pretty open to ideas, I wonder if he would make the pink/white noise tileā¦
Hope this helped and isnāt too obnoxious.
