Hi, sorry I've been pretty much absent from this great forum for a while. Half a year ago I decided to do a black-belt grading in October. Training/workout, regular day work, family and shipping Primovasound stuff (mostly GK cables and MIDX-20) eats up all my time. I hope things will calm down in November.
But I got more gear than I need...and I like it!

Just happy to hear you are alive, well and constantly improving yourself :-).

Spent the afternoon with my GX-2 with the new V2.0 firmware. Added all my seven guitar profiles (there's space for three more ::) ) into the GR-55 and SY-1000 and the GX-2. Even though I just can switch between two GK guitars at a time, now I have all of them profiles in there "forever". So for any upcoming event I just tell the GX-2 which guitar is 1 and 2 and it automatically knows the settings and what GK SET to switch to in both synth units (connected to the GX-2 with a couple of short MIDI cables).

I realize this is overkill for many, but it simplify things for a multiple guitar/multiple synth nerd like me.

Heads up!
For you wanting a GX-2 (the best guitar switcher/synth switcher on the planet) and you feel the price is too high,
there will be a reduced price around 25 Nov (Black Friday).
E-mail with price will be sent out to my existing customers and also posted here.
Stay tuned ;)

Aloha!
     I am a very happy owner of your GX-2. I am also awaiting your GKPX-14 to purchase. I decided to ask you here instead of email in case others have the same question. Can the GKPX-14 input be connected to a GK output on the GX-2,so all 4 units connected to GKPX-14
be effected by the GX-2 ?

Aloha.
With a GX-2 in the chain you may have one or several GKPX-14 before or/and after the GX-2 in any configuration or mix you want.

(The GX-2 does not consume power from GK OUT A and B. The GX-2 IN 1 and 2 allow higher current draw than GK input of a Boss/Roland synth device)

A new batch of GKPX-14 is in production.
The GKPX-14F version contains an additional subsonic filter.

The GX2 is best thing to happen to GK pick up control ever!

Question though, for a Mac using, PC ignorant dummy (;D) !
Is there a relatively simple way to update the firmware using a Mac?

There's ways to run Windows on a Mac but I'm trying to get the code into GumTowns GearGrinder software when can.

The GX-2 Gear Shifter editor app "Gear Grinder" has had a Mac OS update to include the firmware updater,
the firmare 2.1 file is aso included in the download.

So you Mac OS users can now enjoy the updatig of your GX2 Gear Shifter firmware. !!

I've just made a V2.2 on request from a customer.
He has Godin that strangely won't forward enough voltage onto the GKVOL (pin8) with the existing GKVOL impedance of the GX-2.
I have no problem with my own xtSA so it's weird. However added a new menu to be able to set a custom "Gain" to the input GKVOL signal.
Thought this could be beneficial if someone else experience the same problem in the future (or if someone wants to adjust GKVOL knob "touch and feel").

This will not affect using GumTown's new Gear-Grider 2.x software with the new support for firmware updates.

I hope you know he's got a new Mac Editor supporting the V2.x GX-2 and includes firmware update possibility.

I'll make this public soon when properly tested.

Thank you so much for the assistance with the troubleshooting and firmware update. None of it makes sense, especially since the SY would read 100% volume on instrument 1. Thru the GX2 it would top out at 44. I think I will be posting the general question as a separate topic to see what the impressive brain trust of this forum can offer.

There will be a new firmware. Thanks to Chrissie C. I managed to stabilize the MIDI Clock through the pedal. Also I'm going to lower the GX-2 price because there's been a lot of currency changes since the time I built the batch. However right now I'm having problem logging onto my web page. If you feel you want the pedal, hit my at sound@primova.se and I'll give you a much better price than on the web page.

Hey !


One nice thing would be to add a "Mute everything" , programable via MIDI CC ( Or CTL )

Thanx

Really nice product you created there.

The "noise gate" mode helps me a lot with the OSC problems I have with the SY1000

Thanks for this, apologies for being a bit slow... are you saying you need ENV1 rather than the GK mute on the input? as per images
