Turn the Rock Band 3 keyboard into a sampling instrument with the WAV Trigger – robertsonics. The Rock Band 3 keyboard happens to also be a nice battery powered MIDI keyboard controller that you can pick up on eBay for 20 bucks or so.
With a WAV Trigger and a little electronic glue, which I’ll explain in this article, you can make a self-contained, velocity-sensitive, multi-bank sample playback instrument. The Rock Band 3 keyboard buttons and left hand controller allow you to re-map the keys, change sound banks and adjust note release time (sustain) on the fly. I’ll be using classic Mellotron sounds here, but you can easily create your own sample banks using a VSTi software synth. For those of you just tuning in, the WAV Trigger is a high-fidelity polyphonic audio player. It has 14 “voices” to play and mix uncompressed, stereo, 44.1kHz wav files directly from a microSD card.
R. Ghazala The glass in my workshop window is 70 years old. Its thickness varies, and the world outside passes by in fluid, undulating waves. In the cracks of this glass, where a forgotten autumn's chore may have left its mark, can be seen all the colors of the rainbow, refracted splendidly for anyone given to close inspection. The plans, today, upon which the fairies dance are those of the circuit-bent Casio SK-1. Www.loudsound.com-.url.

Classic Schematics.url. DIY » Schematics son aléatoire.url. Here is a link that Roger sent me a while ago.
Its a website by Frans Samshuijzen with detailed descriptions of some mods that he did to a set of Casio SK-1 keyboards appropriately titled: “Casio Twins“. The mods include a full pitch mod with the use of a TI 74LS624 voltage controlled oscillator. It is also worth noting that a 555 timer circuit would theoretically do the same thing, except that the max frequency of a 555 is about 2Mhz and with the LS624 chip the schematics indicate a range of between 1.5 and 10Mhz with a max of 20Mhz.
The downside however is the fact that the LS624 is far more expensive, $2.55 a pop. Still worth every penny considering that the Casio will provide for a full 3 Octave mind melting sound experience, along with longer and grainier recording times.

Muting Transistor Attenuator Circuits and the 2SC2878 by Jim Keith | Among semiconductors, the muting transistor and its audio application is perhaps the most obscure and poorly understood of all. Simple Mixer Schematics. Simple Mixer Schematics PREAMBLE: I've been cooking audio circuits for so long now I no-longer need a recipe. A lot of the theory I have forgotten over the years because I've just gotten to know the circuits by instinct. But this should serve as something of a guide to designing mixers from scratch.
Selected Schematics. Caveats Permission is granted to link to the schematics on this page however I do not extend permission to place copies of the schematics stored on this site on other sites. In other words, you can link, but don't download and place them on your server and show them as yours. Before you go wild downloading these links and buying parts for the schematics listed below, there are a few things you should know.
If you don't feel like reading yourself or helping yourself, you shouldn't pursue building your own boxes. Réalisations Spoutnick Studio. Realisation d'un Circuit Imprimé de A à Z. Simple Passive Tone-Control. I have built up quite a collection of headphone amps and now venturing into higher voltage/wattage amps. My workbench/home office now has a variety of sources and amps, but one DIY item that was missing was an EQ of some sort. I have a few preamps, but I really did not want to add any more gain and noise to an already congested system. I found an answer in a simple but genius tone-control by Tony van Roon ... xtor5.html.
I drew the amp up in Tina and sim'd the outputs and made only a few minor changes. I replaced the electrolytics with Poly film, R5 to 1K, and C2 to .068u for a little more bass. The tone control sits in between two switch boxes (back to back) so that I have three sources to a switch box, tone control, switchbox, the amps. Since the control is passive it will attenuate about -20db at the baseline and the pivot point is around 800Hz.
