MIDI issues: Fractal latency & issues?

You'd have to contact the amp manufacturer. If specific pins in the DIN plug are using the short-to-sleeve switching method, then you would be able to wire an adapter.

However, many amps with DIN footswitch jacks use control voltage to switch various functions, and you'd be able to tell by looking inside the original footswitch. If it has a PCB and complicated guts, it's probably not doing short-to-sleeve relay switching.

I'd caution against wiring or testing any adapter with the FX8 until you know exactly what each pin of the DIN jack is doing.

I've contacted Bugera and still didn't get response from them, I've been patiently waiting but still nothing from them.

And there's nothing on the internet about how to rewire a mini din to a 5 pin midi or a stereo jack. Which is troubling me. So that's why im just trying.

The only thing i can get it work is from crunch channel to clean. That's it.

And I've read the manual like lots of time. And still I can't get it work.

All i know that the crunch channel need 1k ohms to power it up(changing the channel) and 3.3k ohms to lead channel.

I have an idea though which i will try it once i have a free time.

Ok
I have an 18i20 with midi
What do I do to view the midi signals?

you should be able to hook a MIDI cable from FX8 MIDI Out to 18i20 MIDI In.

if mac, install Midi Monitor by SNOIZE. if pc, install MIDI-OX.

here's a vid that shows how to setup MIDI-OX for monitoring
Code:

i use mac, so just open Midi Monitor, select the correct sources - be sure to uncheck FX8 USB if it's plugged in. then send midi data from the FX8 by changing Scenes or whatever. it should show what's coming out of the FX8 port.

The FX8 relay circuits have a maximum rating of 200mA. Please be careful as you can damage the FX8, your amp, or both.

Ok, I think I have my reliability up to over 90-95%
For reference for anyone in the future, I did this on the DMoll:

7.4.2 Single Channel Mode – Automatic Channel Recognition

Your D-Moll can automatically recognize the pedal’s send/receive channel. To get your amp

into the mood (or mode) for this, push and hold “Mute” and then activate any program

change button on your MIDI pedal. The amp will look for a program change and recognize

the channel it is being sent on. Then it will switch to this channel and stay there as soon as

you let go of “Mute”.
​
I wish it was 100%, but it's close enough it may work for me. I put the Scene 1/2 option in the LOOP footswitch which is a quicker fix when there is a mishap.

I have 5150 50w amp with midi coming next week, so that will give me a chance to narrow down the issue as well. I'll try that midi code report to see what that presents.

Thanks to all who offered help!

cool. i'm interested to see the MIDI monitor reports. please keep us updated when you get the 5150. i've worked with some who have no issues with that amp and the FX8. i'm going to place your support ticket on hold until we hear from you about the new amp, if that's ok?

Yea i know, and yes i am careful with them.

And finally i got it work, yay for me! But just two channel atm, from clean to crunch and clean to lead channel.
Still have to figure out how to get it back to clean now.

updates:
The EVH is due to arrive on Thursday (I had it sent to Kruse for mods so it took awhile longer after ordering)
I still need to run the Midi Report
I was frustrate so I put the DMoll away for a few weeks; I took it back out today. It seems to be at or close to 100% if I hang out on the button for a full second or 2 when depressing it. Is there a parameter that can speed this up? Otherwise, besides being too deliberate, it knocks out my F2 button Scene 1/2 because if you press for too long it activates a different feature (sticky scene).

Ok, I have the midi report; same things saved 3 ways here:
https://www.dropbox.com/sh/pobyf2zgi7pa408/AAA7ySf2gQosZz4AaERtZQs4a?dl=0

I was going scene 1, 2, 3 over and over
It seemed to reflect that in the report (?)
If so, does that mean that this narrows down the issue to my DMoll midi chip?
It worked fine before with Joyo, but it's possible it crapped out at the same time I changed over (?)

My evh midi head arrives tomorrow....

it would seem that the FX8 is sending the correct messages and nothing extra or errant. this typically points to another device being the issue.

the EVH should work properly knowing that. let us know! sorry this is getting so dragged out. but the MIDI monitor does say what's coming out of the FX8, and it seems proper.
 
The EVH works flawlessly with the FX8.
I just contacted P Diezel again to see if there is something that can be done.

You said you know of someone else that has the DMoll and it works with no issue? Maybe I can get another midi chip or something to fix this....meanwhile I'll be jammin on the Kruse-EVH; it sounds spectacular with the FX8
 
Hi, I have a DMoll too with my FX8. No problem for changing channels via midi, it's consistent here.
But I've trouble with the latency : when you hit a footswitch, the channel change on the amp is slow and it makes it almost impossible to use it live.
I also have a tech 21 midi moose : changing channels with the midi moose is instantaneous.
Setting my Dmoll on omni mode or on channel 1 brings the same result : too much latency.
Same issue on firmware 2 and 3.0.

Thanks for your help.

That's not latency, but is delayed switching.

Sounds like you're running FX8-Edit. Pause it or kill it altogether, and program change times will speed up a lot.
 
The problem doesn't come from the Dmoll because there's no delayed switching with another midi controller.

That's strange. I've got two MIDI preamps—a Rocktron Voodu Valve and a Roland GP-100, each about 20 years old—that channel-switch pretty much instantly when my FX-8 tells them to.

Try it with a different piece of MIDI gear, and see what results you get.
 
I have a VH4 and I am having the same issue. Using scenes the amp does not respond consistently to PC messages. So I can't count on the amp to change channels when I change scenes. FX8 works perfectly with my RJM products to change channels on my other amps. I also have 3 other controllers that all work perfectly with the Diezel. Weird! I will open a ticket with FAS!
 
We've had some people confirm with MIDI monitors that the messages coming out of the FX8 are exactly the messages expected. It also seems there is a consistent issue with Deizel amps in particular.

It's really difficult to troubleshoot this issue with those facts.
 
I tried the FX8 with a Sansamp PSA1.1 : still a delayed switching. The response seems a little bit quicker than the Dmoll but still impossible to play live with it.
