Will this midi controller work with the artist?

As i have said b4, i know next to nothing about midi. I don't want a big controller with multiple buttons, but i would like to accomplish exactly 2 things....a one button volume boost by either changing the channel volume up a set amount or by turning on the graphic eq pedal with no eq adjustments, just the level control up a bit. Any method would do as long as i could do a toggle on/off function with this pedal. Second, to toggle chorus on and off.

I found a cheap small pedal used that the guy is selling for about 1/3 of it's new cost. I'd appreciate it if someone could tell me if this will w/o a doubt work with the Kat artrist. Thanks. Heres the page with the details... http://www.rocktron.com/midi-xchange.html

Oh, and i do NOT want to accomplish those functions thru patch switching due to the delay between patches, small as i realize it is. If i wanted that i could do it with the latching jack.

I believe that would fit your needs  - but only if you create 2 adjacent Katana Presets with the setting you desire and can use the MIDI X-Change  "up/down" foot switches to toggle between your presets



Its the "sleeper" MIDI foot controller - I find it powerful, although the Expression pedal MIDI CC# transmission  is fixed and not reconfigurable 



on Katana,  MIDI CC#7  = Global Volume, MIDI CC# 17  = FX2 ( Delay on/off)

If you specifically want to control the Katana EQ and Katana Boost level via MIDI - you can "roll your own with as Raspberry Pi or Beaglebone black Embedded CPU board,

or pursue the Primovasound MIDX-20

Like i said, i know nothing about midi. Everything you said is over my head except that i THINK you may have suggested it will not do what i want unless i accomplish it by changing patches which as i said above won't work for me. As to that other thing, thats even further over my head and probably a whole lot more than the guy is asking for that rocktron.

Also, i don't want to control the level and the EQ. What i was saying is i want a simple volume boost whether i do it by switching the EQ on and off with no EQ adjustments, just a level adjustment to make for a volume boost or by switching between 2 patch volume settings. I only mentioned both to suggest i have no idea what that pedal can do but that either one of those or any other function i can toggle on and off with it to get a simple post model volume boost is all i want out of it for that function. Then the second one being chorus on/off which i want to accomplish via just that....chorus on, chorus off. Not via patch changing because of the delay between switching patches. If i didn't mind that delay i'd not even need this, i could do it via the kats 2 latching switch functions, patch 1/2 and band A/B. But i can't deal with the split second silence.

I thought the FX loop trick does the volume thing? Surely a GAFC woukd do what you want?

It does, but it only does that. I need the 2nd function i mentioned, and the GAFC isn't what i want.

If you only want the 2 functions you mentioned here,
1) channel solo boost on/off
2) Chorus on/off

You can easily achieve that with a 2 button foot switch, plugged into the regular old F.Sw/EXP hole in the back of the Katana.
Make duplicate copies of the same channel to Channels A1, A2, B1, B2
Then have A2 and B2 with the Chorus "on", A1 and B1 with Chorus "off"
Then have A1 and A2 at normal volume, and B1 and B2 at boosted volume.

So when you use the foot switches, switch A will do the chorus, switch B will do the boost.
You will have 4 combinations with/without Chorus, with/without Boost (level raised).

A GAFC pedal can also do that, and give you effects access, and Delay TAP tempo control too.

I stated above that i know i can do that, and in fact thats exactly how i planned to use it and i already put it together with powered LEDs and all only to rip my work apart after discovering the delay between switching presets. Thats a absolute dealbreaker for me.

One mans brief 80 millisecond patch change gap is another mans eternity of dead air.

Id get a DOD 250 for clean boost and a Dan Electro chorus pedals ( at my local Goodwill $50 for the pair used) insert both between my guitar and Katana and go gig.

And Add a headstock tuner

gumtown

A midi patch change pedal is then not for you as there will still be the change gap time.

What you need is a 2 button cc# midi pedal,
set one button to send cc# change to toggle Booster on/off,
and the other button to send cc# change for FX on/off.

or this

I need a post preamp volume boost, i already have a clean boost pedal.

I don't want to change patches, i want to turn chorus on and off and turn a post distortion volume boost on and off any one of several ways that the kat has avaliable like post distortion EQ toggle with no EQ change just volume, or change in the patch volume setting, etc etc. Whatever a midi pedal can do. What 2 button CC# pedals are out there? I have no idea what specs to look for to assure it'll work with the kat.

MIDI CC# control is different than MIDI Patch change ( with resulting global mute between patches), MIDI CC# control  should yield no audio gaps on Katana

A Boss FS-6 or FS-7 connected to CTRL1 jack of a MIDX-20 would do exactly what you want after setting it up, but I feel your looking for some cheap way out.

Unfortunately there's no CC for EQ on/off without a MIDX (or various DIY boards). You could instead use the ext. loop CC and put something boosting or damping in that loop.
But I got more gear than I need...and I like it!

But Dazco disdains audio gaps, and has discovered that remote switching the katana FX loop on / off = a brief gap of silence upon each transition of  FX Loop "ON", and FX Loop "OFF" .   Thus he cant use the FX Loop Boost trick for foot controlled Gain Boost.

I would just leave the Katana FX Loop on and use the custom Loop Boost pedal design i mentioned last week ( no Audio gaps)

Thats what i have done for years (i mentioned it in another thread) with tube amps but with a relay so no long signal cables to and from the loop. But it's a lot more trouble than what i'm doing now. I already have a volume boost via the EV5 circuit i built and use with a switch to toggle between normal volume and a slight cut, using the normal volume as my boosted sound. All i'm missing is chorus on and off and i wanted to do midi so i could have chorus on/of and figured i'd also use it for boost rather then have a midi device for one function only and have to have the boost box i rigged up on the board too. But i can see i'm way over my head on this midi thing so i'm just going to forget about it. Thanks for the replies in any case.

Come-on, you give up too easily. ;D where's the fighting spirit?

Do you have a FS-6 or FS-7 laying around?

If so I do a special and sell you a ugly looking (bad print enclosure) cheap MIDX pre-configured for your need.

(Future on, you can add a second dual FS, or MIDI controller for more things, as you grow and learn)

Note: You also need cheapo 9VDC supply for MIDX and FS-6/7 plus a USB cable between MIDX and Kat.

No brainer, just plug the things in and everything works directly.
Email me at sound@primova.se if interested.

Thanks, but i only started this thread because there was a used rocktron midi pedal cheap. Otherwise i wouldn't bother. I'll just deal with manual chorus activation. Maybe in a firmware update they'll consider making the latching switches configurable for different functions.

Ok, got it. Thanks.
