Inside the Minimoog edition.
First board is the classic Moog transistor ladder filter, which is directly coupled to the VCA. This means that the filter drives the VCA with a really hot signal but without clipping.
A good example of hand drawn PCB traces, they don't do this anymore. This was before surface mount technology, hardly anything wasn't done by hand.
Next up we have the VCO board. This is the early version which is less stable in tuning, but allegedly has a better sound. I don't really care about that, but the tuning is better than than the slim phatty, so there's that.
This little white guy with the shiny black cap is the heated transistor pair. The transistors keep each other at the same temperature to provide as linear response as possible. These are used in the exponential to linear converter (to convert keyboard scaling for the oscillators). A common misconception is that oscillators are unstable, when in reality, it's the exp to lin converter, or in cases of the Moog modular, a cruddy power supply.
The envelope generator board, which is why I pulled everything apart. The mini's envelopes worked fine, but there was constant bleed in the output, meaning it never stopped making sound. Still haven't figured out the cause of this.
Lastly, the power supply board. This just takes the output of the power supply, and derives the -10, +10, ground, and other rails for the rest of the circuits to draw from. The bent pieces of steel are the heat sinks.
Launchkey 25 vs Launchkey 25 Mini
I'm thinking about buying pic related, but also thinking about its mini version, cheaper. Is there much difference between the versions?
Looking for a first liece of hardware, other than various midi/dj controllers. What do you guys think about sample-based grooveboxes? I'm considering picking up a used MC-303, but the fact that there's no sampling and limited synthesis is a bit of a turnoff. What are thr best electribe models?
u makin a fuss about the fuckin 5p for a bag shit? I happen to work in a shop that now charges for bags and people who whine about it piss me the fuck off. bags are fucking shite for the environment and it's a good move to give them value.
if somefin else happened vat-wise it's news to me
It's not terribly hard to, but if you're starting from scratch and not using existing circuits and PCBs, it's very very tough. If you're just starting from a kit and want to build clones, sourcing parts is probably the hardest part. Soldering isn't too hard, practice your chops by making cables and messing around on protoboard.
Well no matter what, you have circuits, but premade PCBs are actually cheaper than if you design your own. The only advantage you have is that you have your own circuit, instead of an existing one.
In any case, synth diy is pretty cheap, it's just the learning curve that keeps people out of it.
