This might be the first one to be featured on the site. It was spotted and sent in via M Me.

"This is the original drum machine 'Digital Drums Music' from Dr. Böhm. The machine was built in the early 80s and is in very good condition.

There are 39 instruments stored as samples in 2 ROMs. The device plays 6 voices polyphon and includes the following 20 presets: Pop I, Disco, March, Jive (R & R), Waltz, Jazz Waltz, Twist, Mambo, Samba, Bequine, Pop II, Polka (March B.), Fox Trot, Swing, Slow Waltz, Slow Rock, Shuffle Fox, Bossa Nova, Cha Cha, Tango

There are 3 variations of each rhythm (except for those in the bracket standing rhythms, since these are already a variation), a break, a solo and a fill in. So that makes a total of 60 rhythms, 60 breaks 60 fill ins and 20 solos.

An Auto Fill feature adds after the 4th, 8th or one random beat a fill in one.

The tempo is set with a "+" and a "-" button and changes back to an optimized pace when a new rhythm is selected. Do you want this avoided, you have to press the 'Hold' Button before changing the Rhythm

For adjusting the volume, there is the silver colored pot button.

The output jack is designed as a stereo jack, that means, that some instruments are on right and some are on the left. In order to connect the drum computer with a monophone amp I will deliver a stereo-mono adapter.

The sound is punchy and reminiscent of a Linn drum from the 80s.

The Böhm Digital Drums is in a good condition and works 100%. The machine is clean, but has due to age some cracks on the user panel, which were glued (see photos for reference)"

Roland JP-8080 JP-8000 JP8000 demo

Published on Jan 28, 2020 Polyvox Style

Supersaws... Roland introduced the supersaw waveform with the JP-8000.

via Wikipedia:

"The supersaw is a waveform created by Roland for their JP-8000 and JP-8080 line of analog modeling synthesizers. It emulates the sound of multiple sawtooth oscillators using a single oscillator. The waveform is described as a freerun oscillator whose shape resembles 7 sawtooth oscillators detuned against each other over a period of time.[3][4]

Since production of the JP-8000 ceased, several companies have incorporated "supersaw-like" oscillator algorithms into their hardware and software synthesizers. SUPERWAVE P8 is an example of a software synthesizer inspired by the architecture of the JP-8000, with its multiple sawtooth oscillators. Another is the Supersaw Plus, which has a JP-8000-style interface and a variation on the supersaw waveform that provides 2, 4, 6 or 10 oscillators. In 2005, Access Music released the TI-line of synthesizers, which feature an oscillator type called Hypersaw that is similar to Roland's supersaw oscillator. Roland also continues to produce other synthesizers, such as the SH-201, the SH-01, the Roland V-Synth, and the Roland V-Synth XT that have the supersaw oscillator type. The supersaw gained popularity in electronic dance music, especially with its use in hardcore and trance music."
