Exploring Elektron DIGITONE
video upload by DATABROTH
"I'm a big fan of FM synthesis, and having the technology in a groovebox/sequencer is perfect for how I like to work."
Note I set the video to start when audio kicks in after setup. You can use the player controls to skip around as well.

"Yamaha Portasound MK-100 Multi-Programmable Stereo Keyboard (1984)
The MK-100 is a unique keyboard in the Portasound range, sharing a sound chip with the PSS-260 and 450. This video showcases the features of the rotating Multi-Menu, which allows you to modify the 12 preset tones via the envelope and waveform synthesizer functions, or add a second layer. You can also change the accompaniment and record a performance including a melody line.
All sounds recorded directly from the MK-100 with no extra processing.

"A portable keyboard equipped with a feature that creates voices by combining waveforms and envelopes like a synthesizer.
The 'Custom Drummer' and 'Custom Bass' modes let you program your custom rhythms and bass lines.
The sound of MK100 are unique to this instrument and it remains very original.
It is unique and unlike any other PortaSound.
It is also in my opinion the most interesting of the series..."

Additional Tone Tweakers Listings, also on Reverb
"We bought this and many other items from the Scissor Sisters studio a few years ago when they got rid of their studio. It’s been tested and is working well (see below) and will be tested again prior to shipping, as usual. This unit contains the keyboards of the 60s and 70s expansion card (normally sells for $200 now) and also comes with a roland m-256e ram card (normally sells for $125 now). If this doesnt sell as a package, we may consider splitting them up later.
The value knob feels a little loose but is fully functional. the volume knob MAY (or may not) be a tiny bit loose - we dont have another for comparison so we’re not sure (we normally deal in older vintage synths). Either way, it works fine too. This item is just tested, not serviced. As with all items of this type and age, we would recommend replacing the internal battery and also the battery in the RAM card."

Baldwin DS-50 Discoverer 49-Key Synthesizer SN BC2802487
Note: Auction links are affiliate links for which the site may be compensated.
via this auction
"The Japanese Baldwin Discoverer DS-50 came out in mid/late 70s (pre-MIDI) and features control over the synth sounds plus a built in drum machine. All original knobs are present. Every single function tested and works excellent as intended, this includes every single key. And all keys are level and have a good almost weighted feel to them.
The auto-accompany can be turned on or off and split at the keyboard (rhythm vs melody). There's a built in speaker but it can be bypassed using the audio outs. This makes it easy to implement in your home studio.
They really built instruments to last in the 70s. The DS-50 is made of metal and really well constructed. Original power cord is included. Also included is the hard to find original owners manual as well as the detachable music rack and original travel case."

(Quantum Maverick (circa 530 MB, judging from the storage space left at 22%)
- Rack ears are included.
100 - 250v auto detecting power supply built in.
Power cable included (EU plug)"

Welcome to Bad Gear, the show about the world's most hated audio tools. Today we are going to talk about the Elektron Digitone. Does this digital synth sibling of the Digitakt and Syntakt finally make FM synthesis accessible to synth noobs? Does the awesome Elektron sequencer of this FM groovebox / drum machine make a difference and why is it technically less powerful than classic 80s synths like the Yamaha DX7?
