If you figure it out, let me know. I plan to take mine to my tech soon to have them fix the individual outs that a previous owner did not complete, install Kenton KADI and maybe, some external tone controls.

Some of the CR-78's internal trim pots adjust Volume, Tone and Pitch, the pitch ones you best leave well alone (once you knock them out of tune, it's hard getting them in tune correctly again). If you look closely on the board next to the trimpot you will see what drum voice it is for, it's clearly marked.

But be careful what you are doing, you may lose the original factory adjusted settings for the CR-78. Because if you are tone deaf then it won't sound the same. Suggest you leave the trimmers well alone, if you have no clue what your doing!.

Does accent change the sound or the volume?

The Accent on the CR-78 increases the Volume on certain steps within a pattern.

How many instruments can play at the same time if you use the programable tracks?

Okay Mr FX23, here is a nice big picture of the front of the CR-78, do you see the Red LED lights in the programmer section, yes! then count them and that is the total you get. If you have the user manual, look at the patterns at the back of it, how many sounds do you see... that's right 4 of them! You got it now... yes?

You should really ask all your questions in one post instead of multiple posts within the thread, that way all of them can be answered in one go.

Unfortunately, the only sort of MIDI I know of for the CR-78 is the Kenton KADI, which is simply a MIDI to trigger device. A tech will have to install a mutli-pin socket to the rear of the unit and then attach leads to each of the CR's voices on the PC board.

I've had my CR-78 about 18 years and have only been able to program it in real time with a DP-2 pedal with poor results. I recently aquired a WS-1 and not having much luck with it either since I do not have the WS-1 manual and it's not available from Roland.

The only other option I have found for programming & syncing the CR-78 is a new device from CHD Electronics: http://www.chd-el.cz/index.php?id=435&lngid=en

The 4 sounds in my previous post refers to the number of drum sounds you can have in a user programmable pattern - using either the TS-1 or WS-1 (if you even read it). A midi retrofit will trigger or play all 14 sounds. Analogue Solutions & Kenton both here in the UK, do midi retrofit's for the CR-78.

Actually, it is my understanding (from Analogue Solutions), that only the 11 programmable voices can be triggered with the AS MIDI kit.
Hi

I just had a look at my drawings;

My kit does not tell me which trigger wire is going to which sound. I can’t check that unless I have a CR78 here and fit the kit to see which note is which sound.

if I am selling you a kit, then I cannot test the assignment to ensure it is correct.

Not sure how many, but the kit basically offers triggers for the main sounds only. 10 I think. I don’t think those other 3 are included

The "constant" percussion cannot be triggered externally.

Kenton Pro-KADI has up to 13 triggers.
