About:
iPG-800 is a MIDI Controller iPad app emulating the functionality of the PG800, PG-300, PG-200 and PG-1000 Synthesizer Programmers that were
built by Roland.
It only works with a Roland JX-8P, MKS-70, JX-10 (with Colin Fraser OS or
Fred Vecoven OS), Alpha Juno 1+2, MKS-50, HS-80, JX-3P with Organix or
Kiwitechnics OS and D-50/D-550.
iPG-800 is a CoreMIDI app and connects to CoreMIDI compatible MIDIInterfaces that support sysex like the iRig MIDI (e.g. Alesis IO Dock does
not work) and to wireless MIDI Network sessions.
Setup Procedure:
You can connect iPG-800 to your synth directly with a hardware MIDI
interface or wirelessly using a computer.
Hardware MIDI:
You will need a CoreMIDI compatible MIDI interface that supports sysex
messages, like the iRig MIDI or the Line 6 MIDI Mobilizer Version 2. The
Alesis IO Dock will not work, it doesn’t support sysex.
Alternatively you can use the Camera Connection Kit and a normal USB
MIDI interface.
- Connect the MIDI Out of the synth with the MIDI In of your interface.
- Connect the MIDI In of the synth with the MIDI Out of your interface.
- Connect the MIDI interface with the iPad and launch iPG-800.
Wireless MIDI:
You will need a computer on the same wireless network, that has a MIDI
interface connected.
- Connect the MIDI Out of the synth with the MIDI In of your interface.
- Connect the MIDI In of the synth with the MIDI Out of your interface.
- Launch iPG-800
Mac OS:
Open the Audio-MIDI Setup under Utilities.
In the MIDI-Studio window double click the network icon:
This opens the MIDI network configuration:
Double click your iPad in the directory window:
Your iPad is now connected. Set the MIDI port your synth is connected to
under Live Routings to send and receive MIDI messages:
PC:
You need a program called rtpMIDI. Please refer to http://www.tobiaserichsen.de/software/rtpmidi.html for details.
Synth Setup Procedure:
- Check the MIDI Channel(s) (JX-8P: MIDI Menu 11 MKS-70: MIDI Menu
11, 21 and 31)
- Turn PROGRAM CHANGE on (JX-8P: MIDI Menu 12 MKS-70: MIDI
Menu 13, 22 and 32)
- Turn SYSTEM EXCLUSIVE on (JX-8P: MIDI Menu 26 MKS-70: MIDI
Menu 14)
- For the Alpha Juno push the MIDI button until you get to the respective
menus (MIDI CH, MIDI PROG C, MIDI EXCL)
- D-50: Set Exclusive in the MIDI Menu to P-DUMP
iPG-800 Setup Procedure:
- Choose your synth model on the setup page. For the MKS-70 there are
two modes. Mode A is the normal one and Mode B is the one for older
Firmware (Sends out the whole tone data for every parameter
change). If Mode A should not work, select Mode B.
- Set the MIDI Channel(s) according to your synth’s setting. To change
the control channel for the MKS-70, switch Synth Model to JX-8P and
adjust the channel. Similarly MIDI Channel A and B are adjusted by
selecting Tone A and B respectively.
- The 3 rotary knobs can be set to react to rotary or vertical moves
respectively.
Operation:
Operation is as you would expect. All user controls, i.e. sliders, switches
and knobs, send out their commands when changed and you’ll hear the
effects immediately.
In return, switching tones or patches (MKS-70 only) or changing one of the
parameters on the synth, updates the user controls as well. This is the main
advantage over the real PG-800. Note: This doesn’t work on the JX-10.
The disclosure button in the left upper corner opens a popover, that lets you
switch Tones and Patches (MKS-70) only.
Additionally there’s a MANUAL button, which sends out the value of all user
controls at once. The WRITE Button sends a write command (JX-8P only).
D-50: Handling the sliders by the slider cap sets all the selected values
directly to the value of the sliders position. Touching the sliders elsewhere
without moving, displays the respective value first and moving then changes
the values relatively (when more than one partial is selected e.g.).
More than one partial can be selected for editing. Therefore the partial
whose values correspond to the slider positions is blinking. The common
select buttons function similarly.
The sliders can’t be moved if no partial nor common button is engaged.
The previous value button displays the tone values that were last received.
The manual button sends out only the partial or common data that is
selected by the buttons.
Troubleshooting:
When using a hardware MIDI interface it can happen, that the MIDI input to
the app is not working and thus the user interface elements won’t get
updated when tones are changed. In this case simply disconnect and then
reconnect the MIDI interface.
