Digital Polyphonic Synthesizer Synthesizer

Roland D-70

 Super LA Synthesizer

The sequel to the classic D-50 (even though it was really more like an upgrade of the U-20 – or “U-50” as found on the motherboard).

The D-70 is a wonderful synthesizer, that captures the spirit of the classic D-50, and takes it to a new dimension.  This is a quality synth from a bygone era.

Great features include 76 keys, sound layering, and a very expressive aftertouch.

Like the D-50, Eric Persing and team did an unbelievable job with the sounds of the D-70.  Patches like “Ghosties”, “Prologue” and “SpaceDream” are masterpieces of synth sound design.  The sounds in ROM have a very punchy, full, “complete” sonic character that sounds great even today.  The on-board effects are also of very high quality.

Note: You may need to slow down the transmission rate of the sysex, and the D-70 will receive it.

You can also press 5 when powering up and it will offer the menu to load sysex, but I found you don’t need it really… the D-70 receives the sysex from the main screen as well (which right now you see as a garbled mess – it’s okay).

The key in my case was to slow down the sysex transmission to very slow.

You can use any sysex software you like, but the shareware Bome’s SendSX or MIDI Ox worked well for me:

  1. Go to Options–>Settings and set the “Speed of Sending MIDI” to the lowest position
  2. In the same menu, set “Wrap long sysex messages upon loading”.
  3. Also don’t forget to select the MIDI interface that you are using, in the Bome’s “Midi Out” menu.
  4. Connect the MIDI out from your computer to the D-70’s MIDI In
  5. On the D-70, press Edit –>System Setup and set the “Exclusive RX” to ON and the Unit Number to “17”
  6. Send the sysex to the D-70 –

Analog Polyphonic Synthesizer Synthesizer

Roland JX-8P

Analog Polyphonic Synthesizer

The Roland JX-8P is a six-voice polyphonic synthesizer that came out in 1985.  It is a typical “hybrid” synth of that era, featuring DCOs but VCFs and VCAs.

The sound is – like its relatives JX-10 and MKS-70, very “lush”, classy and full. The keyboard is dynamic and has aftertouch. There are many editing parameters available, and also they typical Roland on-board chorus, and portamento.

Since the synth was built at a time when digital technology had exploded and all synths started looking like the DX7, the JX-8P has no knobs – but relies on multi-functions, buttons and a slider to edit the sounds. The PG-800 programmer can be used to program the synth with a more traditional “analog style” interface. The Roland JX-8P features full MIDI, and also accepts a cartridge to store 32 additional patches.
