Thinking about buying some kind of synth, could maybe make around £250 in the next couple days so that's really my price range, was looking a bit into KORG LittleBits Synth Kit to play around with that working with my midi guitar, got a lot of possibilities with them together, any ideas? also i have seen previous posts on the last page, i'm looking for something more modular for actually creating synths physically
I thought you already had a keyboard or something, what was that? :o
Also, what do you mean creating synths physically? The microbrute, microkorg, mininova, and bass station II all have synthesis engines that allow you to make your own sounds all the way from the waveform to the patching, you don't just play presets.
If you just want more knobs to twiddle with then maybe you'd be interested in something like a Korg MS20 mini:

$600 USD the Korg MS20 mini is a recreation of the older, larger, Korg MS20 which was widely used then and even now. It allows you to get a bunch of cool sounds and stuff just like the old one, yadda yadda yadda, great synth, everybody loves it, etc. End sales pitch.
Just like the Microbrute (or any other non-digitally based brown townog* synthesizers), you can't save the patches that you've made to a preset library (Such as on the microkorg, mininova, bass station II, so forth). It's 100% brown townog.
If you're looking at eurorack modular type stuff then you better open up a savings account. A small beginners lunchbox case alone will cost you $160 USD

A cheap* module system would cost you well over $1200 USD
btw, you're really not gonna want to use the littlebits Korg kit if you want a *serious* synthesizer, those are just fun little modular toys that you'll have a hard time trying to get much out of in the area of synthesis.
