Starting a small modular

Post by sbookholt » Mon Aug 24, 2015 6:38 am

I never looked into modulars, but i realised with the pro2, i only need a vco and a filter right? My plan is to buy a pittsburgh cell 48, with an mfb vco3 (triple vco) and an e-440 filter.
The pro2 can send cv's to pitch the vco's, add envs and lfos. Route the audio back into the pro to use its vca's.
Seems way more versatile than adding something like a minitaur.

Its a great way to go mate but I can promise you your modular will not stay small :D :D ,its like an obsession to make it grow and grow but you will love it.I brought a Doepfer A100 mini system a year ago and I have already filled the free space up and need another case to start filling up :lol: .All the best Glyn.

Yes it feels like starting a meth addiction or something like that :) I'll try to keep it small. It's just after so many synths I always had the feeling like if I could use the filter of synth A, but the modulations and oscs of synth B and the envelopes of synth C it would be perfect. Now I can make that.

Do you also have the e440? The most interesting filter I've heard so far on any synth.

Looks cool, the a120 sounds really nice too... Have you tried it with the pro2 taking care of the lfo's/envs?

Well in theory you could get a VCO or two and a mixer and use the Pro2's build in filter via external input and modulation for the rest of the sound. But there are many options and all of them costs a lot of money!

Yes mate,it makes for one pretty impressive synth/synths 8) :D

I hate to break it to you, but there is no such thing as a small modular :)

It's a bit like crack. Rather moreish :P

I think this will be my starting point: https://www.modulargrid.net/e/racks/view/202197
But I've read euro signals are much hotter than line. Will the audio input of the pro2 be able to handle the modular audio out? Otherwise I need to add a VCA.

Much hotter than line levels, they can we well over 7 times more voltage.

I did have an email conversation with Carson about this but can't seem to find it.

My memory is that the CV ins are ok up to 10V but the audio ins are not. It might be worth you emailing DSI support.

A cheap and useful module is the Doepfer A183-1, this is a dual attenuator that can be used to lower voltages down to line level.

The A183-3 is also useful as It can amplify as well as attenuate. This can be useful for boosting line level outputs up to Eurorack voltages.

I'm happy with the Pittsburg Foundation synth I have. It does sound great so you won't be disappointed. I had not really considered the CV abilities of Pro 2 when I bought it and now I have the two instruments spaced too far apart in my studio to make the kind of idea you discussed work :? I gotta re think this set up.

Another n00b question, When I sequence the pro2 from a DAW, will it send the pitch cv's of the sequenced notes to the modular?

Yes mate, it does, just tested with my Pro 2 being sequenced via VSS 2.6R (Reaktor) with Seq.track 1 being sent to CV1 then feed into my doepfer and it works fine.

Good luck! My impression is that the eurorack modular world is like a bottomless swamp so watch out but do have lots of fun. Oh and please consider setting money aside for very basic boring things like food and rent.

I saw this interview with one important module maker which may be of interest and inspiration for you:

Cool thanks for confirming Glynbo!

I've read the article, interesting! I've put aside at least one month of rent and food so I should be good :)

Got the case and mfb osc-3 today. I can confirm it works perfectly plugging it into the pro2 cv's and audio ins. The pro2 has a built-in attenuater, the eurorack levels can easily be matched to the inner voice.

I think it's highly recommended. For 229,- (plus a case) you can extend your pro2 with the osc-3, which contains 3 vco's, pwm, ringmod and sync. It sounds very thick and warm. You can assign the note number to cv1 in the mod matrix, patch that into the osc-3 and you are ready to go.
I'm going to add a bunch of other stuff, like filters, mutable instruments clouds and some other stuff in the future, but with only 1 module it's really nice already

Congratulations with your modular extension to Pro2. Would love to hear some sound samples one day (youtube works best here). I have always loved the idea of extending Pro2 with analog oscillators due to its warmer sound. Can only imagine what four digital oscillators plus the digital sub and the three VCO's would make for a kind of fat bass or lead sound. Watch your speakers! :-)
