Roland TR-999 KORN HARDCORE CUSTOMS TR-909 Mod
Duration 10h for Mods: 600€ +Parts and postage (german clients +19%)
Spring 2020 new full length video!
Completely reverted the previous work. NOW it feels like my very own 909. Notice that signatures from Jeff Mills and Juan Atkins that i was lucky enough to meet during gigs.
So the final list of modifications is almost endless since the great nava extra 9 project and Robin Whittle documented a lot of other stuff that i needed to try out. I was actually ok with it now to not being able to switch every mod on/off. But you can dial in the stock values still. Plus i needed that replica knobs that really look great on the machine now. Was some extra work to fit in the support boards for the d-shaft knobs but totally worth it.

Anyways, here is the list:
-BD Pitch R59 (100k lin + 10k)
-BD Tune Depth R28… (220 kB+Trim)
-BD Overdrive R52 (10 k lin + 1k)
-BD Tune Range (C9 1uF, R21 1k R57 10k paral.)
-BD Decay Range (C8 1uF parallel)
-SD Tune Range extended R284, R287 (4,7k 47k prallel)
-SD Tone Range extended (Noise Decay) R254=100k: 10k replace or 10k parallel
-SD Snappy Boost R294 (22k parallel) Trimmer: boosted the mix level of the output of the Snappy pot (13.4k instead of 47k, leading to 3.5 times the signal level, which is about 10dB)
-Switch Snare Decay exponential C68 is removed, which eliminates the 24 ms flat start to the envelope
-Tom Tune Range extended R112 10k Original parallel 4,7k and R113 68k orig parallel ca. 30k
-RIM Tune R414 (1M rev log )

Also exchanged the eprom to the latest firmware (V4) with stable MIDI timing. Thanks to curetronic for the steady desoldering-hand:)
