Roland TR-505 stuff

Points for individual outs (audio signals-add ground from ground point)


Points for bit-crushing effects: just solder to leads and strike them against the other at pleasure.. i dont like bending stuff, but this is the way it came when i bought it second hand..

I bought a ROM expansion that adda DMX, LINN DRUM and LN1 sound samples.

Desolder IC11

Solder the ic socket

Solder the switch to the pcb

All done! 

You can buy the expansion here:

Catalinbread Heliotrope knock off

In a couple of days i put together the Heliotrope (a ring modulator in my book), as per Sabrotone layout..
(remember the useful comment as posted by someone to modify the switch:


(Thanks to the original poster at Sabrotone, and the legendary IvIark for the original wiring layout) otherwise it will whine even when on bypass)

Though owning Electro Harmonix’ Frequency Analyzer in the big sexy old school case already, i did not really need another ring mod.. Nevertheless, here ’tis.. just press play on tape



8 bit flavor since it is supposed to crush code ahahah
