"This is a heavily modified and circuit bent Alesis HR 16. The basic idea is that you can change the eproms and then mangle the sounds into oblivion by way of the knobs and switches which create all sorts of unpredictable and fairly brutal noises. The result can be anything from utter industrial magic to unusable garbage. Comes with a number of eproms incl. Korg, Linn DMX, Roland The machine is very unstable. Sometimes it works sometimes it just doesn’t. I have no idea how to make it more stable and when it comes on and produces sound, it’s absolutely random and unpredictable. The best way to think about this is as a sample source in that you have a tape running all the time and then pick and choose the best noises that come out of it. The great thing is that you would never ever come up with these sounds if you were to program them in a targeted and controlled manner. But on the other hand, it’s of course frustrating when it doesn’t come on at all. The starting bid is set accordingly. The buyer may wish to have a technician take a look at it."

"Rare 808 drum machine clone https://www.soundonsound.com/reviews/acidlab-miami An analogue clone of Roland’s TR808 for much less. Generous pattern capacity. Can switch seamlessly between pattern selection and programming. Syncs to MIDI or Roland’s Sync24 protocol. Individual outputs for every voice. COMES WITH UK 3PRONG ORIGINAL POWER SUPPLY as sent by KLAUS small print in panel has faded in places . But its not apparent much. a small scratch here and there (the one looking like a hair scratch on one pic under step 14 is actually hair and not a scratch!!) But if you look closely on the bassdrum decay konb the lettering has faded slightly. There is also an actual scratch on the LT/LC switch. things like that make it a 'near good' condition but not perfect. Its a 15+ old machine so I guess little things like that can be expected and are described upfront so no surprises. These have become quite expensive on ebay so this is a chance to get yourself a nice 808 for no primetime $$$$"

Solist 🎸(Roland JD08 + Bigsky + Pill // SE02 + H90 // TR6S // Erica Synths DB01 Bassline + Lethargy)
video upload by 2-Minute Warning
"Let's go for a 5-Minute Warning video, with some real-time guitar-like sound solo playing! 😊
0:00 - Scene 1: Intro starts with the STRINGS (JD-08), ARP (SE-02) and DRUMS (TR-6S)
0:46 - Scene 2: DRUMS knob reload for big sound + BASS (DB-01)
1:17 - Scene 3: SOLO 1 improvised (JD-08)
2:02 - Scene 4: Bridge
3:04 - Scene 5: SOLO 2 improvised (JD-08)
3:50 - Scene 6: Outro
Some tips used here:
TR6S (DRUMS): I used the 'KIT KNOB RELOAD' feature to get back to the big drum sounds as it was saved in the kit (I previously moved the knobs to pitch up/down and reduce the decay of all the sounds for the intro)
TR6S (DRUMS): the VINYL SIM effect is used on the TR6S' master bus to heavily compress the DRUMS
TR6S (DRUMS): I used the internal LFO to modulate a few parameters on the DRUM tracks to add some subtle variations
KEYSTEP PRO (Sequencer): I used the Chain feature to chain 2 patterns in order to have an 8-bar pattern for the ARP sequences
KEYSTEP PRO (Sequencer): I used the Scene feature to load different patterns and mutes in one time (to switch to the bridge for example)"
