Guest rasteri Posted July 16, 2016 Share Posted July 16, 2016 I input the TR-808 kick drum in a circuit simulator (LTSpice) and left it running for ages (took over an hour to simulate a few seconds) : So here's the resulting .wav, probably the most cleanly-"recorded" 808 kick in existence : https://drive.google.com/file/d/0B7FEmphzxtnxREhoS3pJZDVTOXM/view?usp=sharing Sounds great with a little distortion and compression. Might be fun to try virtually circuit-bending it next. We'll see how things pan out. 6 Quote Link to comment Share on other sites More sharing options...

Mutis Mayfield Posted July 18, 2016 Share Posted July 18, 2016 If it's possible adjust component specs maybe you can make the resistors germaniun based. Maybe this is what Roland calls ACB tech for their Aira machines. Quote Link to comment Share on other sites More sharing options...

Maybe this is what Roland calls ACB tech for their Aira machines. As far as I can tell from the schematics Roland just used normal resistors and silicon transistors/diodes in the original 808. I think the ACB stuff is their way of doing a much more optimised version of this same circuit-simulation approach, with some added randomness to make it even more analoguey. 1 Quote Link to comment Share on other sites More sharing options...

DJ Rock Well Posted July 19, 2016 Share Posted July 19, 2016 Damn Rasteri, you are killing it. Perhaps you could gradually work through all the 808 drum sounds, so I can slowly collect them all until one day I have a whole one? Quote Link to comment Share on other sites More sharing options...
Flexinoodle Posted July 19, 2016 Share Posted July 19, 2016 Next stage of the project arrived this morning That's just the control panel right, controller for the simulation running on something ? Quote Link to comment Share on other sites More sharing options...
Guest rasteri Posted July 19, 2016 Share Posted July 19, 2016 That's just the control panel right, controller for the simulation running on something ? It's the whole analogue kickdrum circuit. Most of the components are going to be surface-mounted on the underside : 1 Quote Link to comment Share on other sites More sharing options...

Guest rasteri Posted July 20, 2016 Share Posted July 20, 2016 I'd have to charge quite a lot (like £150 or so), and that would just be for the assembled board with no enclosure, although I'd give it a rubber/foam base to protect the components. Would people be interested at that price do you think? Quote Link to comment Share on other sites More sharing options...
Guest rasteri Posted July 20, 2016 Share Posted July 20, 2016 Also I did toy with the idea of doing a run of 200, which would get the price down to maybe £100/unit (again just an assembled PCB with no enclosure), but I don't know if that many people would be interested, and I'd obviously have to raise a few grand first (maybe kickstarter). 2 Quote Link to comment Share on other sites More sharing options...

DJ Rock Well Posted July 20, 2016 Share Posted July 20, 2016 I'd definitely want one. Obviously £100 would be easier to swallow than £150, but we all know you'd charge fairly based on costs, time, etc. I think your KS suggestion is right on the money for this one. It's kind of niche, but I'm sure there are 200 nerds out there who'd gladly buy this. Looking at the money people spend on synths old and new, boutique pedals, etc. This is not big money in that world and I think it would fit in nicely with all the affordable small synth type modules out there that are popular right now. 2 Quote Link to comment Share on other sites More sharing options...

Guest rasteri Posted July 20, 2016 Share Posted July 20, 2016 Suppose I'll start small, sell the first half dozen for £150 each and see how that goes. 2 Quote Link to comment Share on other sites More sharing options...
