How do I control TG-500 parameters on my controller?

The Yamaha SY85 is a digital music workstation introduced in 1992. Unlike other Yamaha synthesizers of the time (SY77 and the SY99) the SY85 does not use FM synthesis. Instead, its sounds are based on samples, which can be layered and modified to create new sounds.

How do I control TG-500 parameters on my controller?

Unread post by Amalgam » Mon Mar 11, 2019 2:56 pm

For days I have been trying to figure out how to control basic parameters like ADSR, Cutoff, Reso (etc.) from my controller to the TG-500.
The controller is an Arturia Keylab and I’m using Logic Pro X on a Macbook.
Can someone explain how to do this? I’m sure others also had to deal with this problem.

I’ve been reading the manual and MIDI implementation chart over and over, but I can only vaguely understand the procedure.
I believe I should do something with SysEx messages within Logic (in an Event Editor), but my understanding stops when I’m supposed to type in certain strings of numbers in SysEx Hex Format.

MIDI controller assignments are made via the “UTILITY” mode “2:Controller” screen.
The four parameters provided in this screen allow any MIDI control device numbers
to be assigned to TG500 controllers MC1, MC2, MC3, and MC4. (p.223)

In Voice Edit Mode, “MC3” (MIDI Controller 3) and “MC4” (MIDI Controller 4)
can be assigned to control a wide range of voice parameters in real time.
Also set minimum and maximum limits % of the control range. (p.147)

Some examples:

1.Controlling “Total Level 50% ~ 100%” with CC018:

Utility mode, MC3:018 - Voice edit, MC3:19 Total Level, min 50% max 100%

2.Controlling “Filter Cutoff Frequency” with CC109:

Utility mode, MC4:109 - Voice edit, MC4:57 FLT_CofFrq, min 0% max 100%

3.Selecting "Voice Preset 1, 028 BR Horn" on Midi Ch.1:

Midi message: B0 00 00 20 02 C0 1C

4.Implementing “LFO speed parameter 104, value 70” on Midi Ch.1

Midi message: F0 43 10 29 02 00 00 68 00 46 F7

Thanks for replying Sonus. From this info I understand that the TG can only communicate with 4 sliders or knobs of choice. But does this mean it is not possible to assign as much parameters as available for the controller?
(The Keylab has 2x10 knobs and 2x9 sliders).
Or is it possible, provided I work with Midi messages within the DAW environment?

You're welcome, midi control change data can also be assigned to control two effect parameters in real time (p.213).
System exclusive messages can be implemented in a track but too many data could generate buffer overflow.
It's actually for editing a TG500 while all notes are off so it doesn't replace continuous controllers...

Yes, I’m aware it’s possible to assign a few parameters to CC numbers on a controller. However, 4 parameters (+2 for effects) is extremely limited.

What I would like to figure out is how to use my controller’s filter and amp ADSR (already 8 parameters), and next some basic functions like Cutoff, Resonance, Chorus amount and Delay amount (4 more). I assume that Chorus and Delay can be handled by the two available MIDI CC for effects, but what I’m really looking for is how to expand my controller’s potential.
I hope to get a better insight with helpful directions from the many TG500 users before me.
