Your preferred non303 synths/filters for 303 type sounds?

example of a little zappy synth sound from an EWI3020m turned into some acidish lines with the help of the digitakt.

it does feel a bit odd to try to program that sort of thing without proper slides though.

I’m liking the acid type sounds I can get out of my newly acquired SH01A. I’ve also had decent results with my Bass Station 2.

i have a re 303 and a Oberheim SEM, the SEM can get there but fatter, early CHemical brothers use a SEM for the acid.

I remember when selling the sh01a I was under the impression that I could cover most of its sound with the A4.
Would be nice if there was a good soundpack mimicking vintage roland sound, since everyone seems to be after these sounds. me included :slightly_smiling_face:
I remember you saying you prefer the second filter on the A4. Do you think it is closer to Roland filter sound?

Analog four does a brilliant job!

If you have one, try for yourself: Analog303 kit : ) (AND dual303-kit)

If not, you can listen here:

Microfreak does a good job as well:

Good memory! Mostly I’d say the SV filter on the steeper LP is my goto for things like SH, TB-303 and Juno type sounds, although I do sometimes use the LPF for Roland style sounds, then the SV can be used to carve out a bit of the bottom end if needed.

I did intend to do a classic house/classic Roland soundpack a few years back, unfortunately I never got around to it, but I should get back into it.

I even did an emulation on the AK of a little known *TB-303 hack, where plugging the CV into the Gate results in kind of a fast modulation of the filter, I mapped the joystick up position to emulate the sound that this hack produces :wink:

*Not recommended, BTW if anyone thinks of trying it on their vintage 303 do so at your own very real risk of damaging it. Don’t do it!

Nord Lead A1.
Its TB modelling mode, freakishly similar. Kept me amused for days.

The Monotribe can glide.
Set the pitch to wide and program one step (record) with the other 7 turned off , then go back to equal temp pitch and record the other steps .
Set flux mode on for play back.

The seq gets some wicked bends like this, just wiggle that finger.
Turning 7 steps off is also good for full step recording.

another vote for the venerable MS-20 filter here.

The Moog M-32 can do some cool acid stuff.

also just got an M.I Ripples filter for the old eurocrack set-up - that seems like it could do some acidic damage… Must investigate further…

Ripples is beautiful.
People say it‘s very Roland SH sounding
Never owned a real SH synth so can‘t comment, but I loved the sound of ripples

Electribe 2 (synth) at the moment.

in particular, E2 has very cool emulation of MS-20 filter, i often prefer it to „Acid“ (303-like) filter emulation due to stronger resonance.

The MS20 in the right setting can be very acid

i like it on this guy‘s jams a lot



very afx

My fav synth for acid lines lately has been the Shruthi with SMR4MK2 filter.
Sounds more 101 than 303 ofc, the SMR4 filter was meant to replace the filter boards for IR3109 ics (afaik the IR3109 ic was in the 101), but it just sounds soo lovely. Especially in tandem with my AK.
One day, I’ll do the Sound Designer Mod. From the demos, that’s pretty much acid heaven.

What else? Volca Bass (slides lovely!), Monotribe (awesome filter + audio range lfo) and FM synths! Usually FM8 with midi control of the algo matrix.

Imho it depends. For some rolandish sounds, I definately prefer filter 2, for some filter 1.
Then there’s also resonance boost for filter 1.

At first dialing in rolandish sounds on my AK turned out more difficult than I thought, though.
Could be because I was using mostly filter 1 at first, dunno. It certainly took me quite a while!
Using macros definitely helps. Also visualising what the synth I’d want to emulate has in terms of synth architecture and on board controls, how the signal flow is and what it doesn’t have and then restricting myself is a good starting point.

Never had a Moog, what’s the difference?

Older Moog stuff used fixed rate so longer distance between key means longer time for the glide while 303 used fixed time, so longer distance slides have the feeling of moving quickly. Obviously lots of synths used both these but for some reason my brain categorizes them as moog or 303 style glides.

Thanks for reminding me, I need to reload that!

That’s a great patch! Thanks again for making and sharing that! :slight_smile:

The A4/AK make excellent acid sequencers for CV gear like the MS20, you can use the note slides, and for accent use a CV envelope or LFO or whatever else takes your fancy. Highly recommended fun.
