My advice on any musical equipment is that given to me a while back: “How are you going to use it musically”. I see all synthesizers and effects, be they digital or analogue, as tools and you don’t simply buy a tool because the tool looks good.
I to will probably buy a modular but only ini pieces. I have certain sounds that I want to experiment with and a modular is probably the only way to get there.
The advantage I see in modulars is that they are extremly flexible. You can plug everthing into everything (sort of). The downside of this is that they often need to be tamed. If you are more into a circut bending sound then you will be happy with just fiddiling with knobs, however, if you want to be more refined its going to take some work.
I have heard the bleeps and bloops arguement about modulars and frankly, at times I find that a valid point. If you go to the internet you will hear for the most part, bleeps and bloops. Most of the videos I see are of people running a sequencer and then twisting knobs to get a differnt sound. That’s pretty marginal music if music at all.
Now consider Pink Floyd’s famous on the run that is duplicated in many places on the net. Remember that they added sound effects to this and rhythm. They made it work musically. It was not just using a synthesizer for the sack of using a synthesizer.
One of my favorite “pure” electronic artists is Morton Subotnick. Subotnick’s technique used what he called “ghost tracks” which are similar to MOTUs volta. His music is a long way from bleeps and bloops. It refelect careful composition and musicality. Of course, he is using Buchla which for most people financially is not possible including myself however much I would love to have a 200e which is an incredible blend of MIDI and analogue.
Ask yourself the simple question: “What sound will a modular give me that I don’t have now that I will use in my music”. Then build a system around that answer.
I regards to foogers and the CP-251. Foogers are modular like. I have mine all mounted on a rack (incl. the CP-251) with a single Vodoo Labs power supply. What they lack are triggers. They make up for this with envelope followers a bit but even with the CP-251, they will not really function as a modular because they don’t have any VCAs with trigger inputs.
The Voyager expansion unit will give you some access to applying CVs and using CVs from the Voyager but again, you are not going to have a full modular.
The advantage of modulars is that you can build them and mix and match. Many people are into the .com format but I find thiis limiting. For example, in my case, vactrols are important to get a Buchla type sound. I also like a lot of the filters I see out there and they are not always in .com format. I will probably go with eurorack for this reason. I am always thinking in terms of application. What sounds do I need?
As far as getting rid of the Virus, again, look at your music. If you sell it are you going to lose something vital to your music. While I do like some of the modular sounds, I have a Korg M3 and I would never consider selling it. It has an incredible keyboard, you can modulate just about everything and it has a wide range of controller options including the touch screen itself which doubles as a controller not to mention KARMA which is a whole new world. It also have a killer group of effects which can also be controlled by all the modulation sources and a modulation mixer.
Also keep in mind that you can’t save patches on a modular. This is limiting. I was disappointed when Clavia droped the Nord Modular which was in many ways a best of both worlds option. I would have bought one. You may also want to consider Native Instruments Reaktor. Think of the software version of the most sophisticated modular you could ever imagine and thats Reaktor. If you want some wild sounds and you have a computer, just get a few of the cheap Kore packs and you will find a universe of sounds you probably have never heard.
Now is Reaktor the same as a modular? Not at all. Analogue circuits react differently than digital and if I did not believe that I would not have a rack of foogers and be considering a modular.
All I am trying to say to you is think musically. I am a composer of experimental music and I always try to think in terms of concept. What am I trying to create. If soft synth works, great, if hardware digital works, great, if modular works, great. Its all a matter of the right tool for the job.
Best of luck with your foray into modulars but don’t be impressed by lots of technical stuff if it does not work for your music which is really the goal.
