This is all about modding and tweaking the hell out of various hardware. Be it a toy synthesizer or some pro gear - there's always a room for improvement.

While circuit bending process, to be successful, generally calls for a person completely unwise in electronics, there are still some nice things that professional electronicans can do about it. That's ok that we are unable (just can not from a moral standpoint) to short completely random circuit points with wires, as well as we do require extremely overdone reasoning above curiosity - we can still have some fun.

 

	Synthesizer & other gear internals Yamaha synth chips (pinouts - many of which nowhere else to be found) Korg synth chips (mostly random rambling about their DSPs) Roland wave expansion cards (yep) Pinpointing problems in Юность / Юность-16 / Юность-70 and getting them back to life Alesis M4 & M4C DSP chip (used in MidiVerb 4, MicroVerb 4, NanoVerb e.t.c.) RMIF TI-3 / TI-5 soundsource internals, ROM images and repair tips Texas Instruments TMS57070 DSP chip (found in many fx boxes of various manufacturers) Лель ПСР soundsource internals, ROM images and repair tips Лель DR-8 soundsource internals, ROM images and repair tips Casio CZ-1 cartridge internals and ROM dumps Casio ROM Pack dumps and song binaries extracted, PT-50 tape loadable goodies
	Synthesizers, effects and companies Roland INTEGRA-7 (I am disappoint...) Roland FA-06 / 07 / 08 (don't buy it until they fix their stuff... v2.01 firmware still poor) Audio Centron FXP
	Programming the vintage stuff Commodore Plus/4 C16 264 TED note frequency tables (ones that are correcty calculated) Casio Loopy game console (synthesizer part in it is actually a standalone keyboard) Yamaha Playcards (internal format and stuff) Yamaha PSS-101/102 and PSS-103/104 barcode card system Yamaha PSR-40 as a fun Z80-based synth with GE7 pre-FM soundchip (disassembly)
	Technology and just some interesting stuff Roland DJ-70 staff display TC-Helicon flavor of ADPCM Common yet obscure mistake in IMA-ADPCM implementation - persistent human typo still around from the last century that I've found How certain cheesy aspects of DTMF likely came about that no one told you about
	DIY gear Controlling Yamaha OPK (YM7116) and OPK2 (YM7129) synthesizer chips.
	Homebrew gear Home brew electronics articles coming soon...
	Why is it even here..? Mickey Mania - Timeless Adventures of Mickey Mouse on Sega and its beta version - all level layout maps and backgrounds decompressed right from the cart and more Most of Puggsy level layouts/maps and backgrounds decompressed right from the cart
	Undeserved attention to unnecessary details DTMF in various movies and TV series - what's being actually dialled There should be some more stuff someday, though this section is no priority whatsoever.
