An acid box with program changes?

Considering buying a 303 clone (again). But hard to figure out if there are boxes that can do program changes (from AR to acid box)

Any experiences here?

Well I think 303 is such a simple thing that it doesn’t really need - the charm of it is that you can be really expressive and play it with closed eyes … after you get used to it it became more like a guitar or so, you just think of a sound and immediatelly know to to get in with those 6 knobs

But if we talk about analog synth modules, I would suggest DSI Tetra, Mopho, Micromonsta 2, Typhon and all other nice little things. They all good with

Thx. Well, I noodled on my XD a bit to come close to a 303 sound, but I think then you really miss slides and accents.

I was thinking along the lines of building a techno/acid set on my AR and bringing in a couple of different 303-patterns. Then program changes really seem handy?

According to the Roland TB-3 MIDI implementation chart, it actually recognises program change. But I’m not sure if that rather weird device can be considered an acid box.

Haha, yeah… I watched a couple of youtube video’s and they are dead cheap used, but still not fully grasping what I would buy if I got a TB-3.

Bassbot V2 works with notes (outside the note range) to select patterns. The cool thing is, if you have a 16 step pattern and play a 1 bar long note for this pattern, you simply have it play the 16 steps, but you could also send 1/2 bar for an intro, or mix two patterns if you like.


Malekko Manther is way more 101 than 303 but has a lot of this functionality and is a lot of fun.

Erica Synths DB-01 had program changes added with a firmware update.


I like the uno for acid
When in single osc mode… with its 24db filters and glides it can get pretty acidic
And has program change

x0xb0x accepts program changes.

Also, the x0xb0x OS code is open source. I modified the OS on mine to accept CC #0 to change programs so that I could sequence program changes from my octatrack without relying on parts.

Would I be able to replicate slides and accents on my XD? (it does prog chng brilliantly in combination with the AR, but I just couldn’t get close enough to the sound myself. Although it has a couple of presets that are 303-style).
