Playing with the SYSTEM-1
By connecting the SYSTEM-1 to your computer (Mac/Windows), you can use the PROMARS in conjunction with the SYSTEM-1.
Windows
The "SYSTEM-1 CTRL" shown as a MIDI port is the port used by the PROMARS. Do not use this port from your DAW.
Plug-Out
What is a "Plug-out"?
"Plug-out" is technology that allows a software synthesizer such as PROMARS to be installed and used in the SYSTEM-1.
- You can play the PROMARS on the SYSTEM-1 by itself, without using a computer.
- You can send the setting of selected bank to the SYSTEM-1.
- You can use the knobs and sliders of the SYSTEM-1 to edit the sound.

Plug-Out Procedure
-
Click the [PLUG-OUT] button.
A confirmation message appears. -
Click the [OK] button.
A progress bar appears, and plug-out processing begins. This takes approximately one minute.
* If another software synthesizer is already plugged-out on the SYSTEM-1, a confirmation message appears. Click the [OK] button to continue.
If an error message appears, check the following items.
• Is the MIDI port specified correctly? (p. 9)
• Is the SYSTEM-1 connected to your computer?
Send/Get Memories

- Connect the SYSTEM-1 to your computer.
- Turn on the MODEL [PLUG-OUT] button of the SYSTEM-1. * In order to send or get a memory, you must first plug-out (p. 8).
Sending the Memory
You can send the current PROMARS memory to the SYSTEM-1 and play it on the SYSTEM-1. The sound is output from the SYSTEM-1's OUTPUT jacks.
- Click the [SEND] button of the PROMARS.
The memory is transmitted.
Getting the Memory
If you've used the SYSTEM-1 to edit a memory of the plugged-out PROMARS, here's how to load that memory into the PROMARS.
- Click the [GET] button of the PROMARS.
The memory is loaded.
If an error message appears, check the following items.
• Is the MIDI port specified correctly? (p. 9)
- Is the SYSTEM-1 connected to your computer?
- Is the SYSTEM-1's MODEL [PLUG-OUT] button turned on?
• Is the PROMARS plugged-out on the SYSTEM-1? (p. 8)

Setting for the SYSTEM-1
When you want to play the PROMARS's sound (plug-in) with your SYSTEM-1, set the SYSTEM-1 to the MIDI controller mode.
Once you set to MIDI controller mode, SYSTEM-1's internal sound can not be played, and the SYSTEM-1 can play the PROMARS's sound only.
* These settings are not available in SYSTEM-1m.
- Turn the power on of the SYSTEM-1.
- While holding down the MODEL [SYSTEM-1] and [PLUG-OUT] buttons, use the SCATTER [TYPE] dial to set to MIDI controller mode.

| Setting Explanation | |
| MIDI Controller Mode | Choose this if you're using the SYSTEM-1 as a MIDI controller.* Playing the keyboard will not produce the SYSTEM-1's internal sound.* The SYSTEM-1's internal sound is not produced even if the SYSTEM-1 receives MIDI. |
| Local Control ON Choose this when using the SYSTEM-1 on its own. (Default setting) | |
| Local Control OFF | Choose this when using the SYSTEM-1 in conjunction with your DAW.* If the SYSTEM-1 is used by itself with this setting, playing the keyboard will not produce sound. |
About PROMARS

natural_image
Front view of a PROMARS COMPUTORIO robot keyboard with control knobs and no visible text or symbols on the device body.The PROMARS was a two-VCO monophonic synthesizer that went on sale in 1979.
It was a sibling of the JUPITER-4 that went on sale about the same time, and its thick sound and the "compu-memory" function that allowed these sounds to be stored and recalled made it highly regarded as an instrument for live performance.
Although the PROMARS was designed as a two-VCO monophonic synthesizer, the pitch of the two VCOs could be slightly detuned to produce a unison chorus effect, and a sub-oscillator was provided on each VCO, making it possible to produce sounds similar to a four-VCO synthesizer. Its rich and dense sound is still loved by both professionals and amateurs.
