x0xb0x x0xi0 Full Mod 2

"Demonstration of x0xi0 Full mod.
This is a basic pattern using two VCO's and noise source. Also, filter tracking, Envelope 2 routed to the VCA and VCF, and to VCO2 as well at one point. I'm also adjusting the VCA envelope parameters. The dedicated VCA envelope, ENV2, and the Accent sweep can all affect the VCA simulateneously - this is where all those syncopated sounds are coming from... where all VCA control sources mix and match to shape the volume.

The row of four controls at the bottom right is the VCA envelope, A - D - S - R
the row of four knobs above that is Envelope2 (ENV2 for short). The first two controls are Attack and Decay/Release. The switch below the second control is the Decay/Release mode switch. The 3rd control in that row is the ENV2 depth amount control. This determines how much ENV2 is sent to the VCA or VCO. The switch below the control allows you to select VCA or VCO as destination. The fourth control in that row is the ENV2 to VCF Depth control. It determines the amount that ENV2 effects cutoff frequency. The slide switch below the knob is the ENV2 invert switch which inverts the envelope shape.

The filter tracking control is the one just to right of the bank knob. The noise source level control is the one to the left and above the tempo knob.

I'm also using the Gate on switchs with the gate on modes. There is a gate on mode that leaves the gate open and only re-triggers the filter envelope and the new ENV manual by pressing that push-button on the lower right. The is a second gate-on mode that leaves the gate open but allows the normal filter envelope to retrigger with each note but not ENV2. In this case ENV2 can only be triggered manually, which is what you see me doing when I press that button at the lower right."

x0xi0 Full mod kit for x0xb0x is now available

via Brian
"It's been 18 months since I showed the [not so] final prototype ;)

I've made several improvements to the original feature set and added some very useful new features. The Full mod kit consists of the Top panel mods and the Rear panel mods. The Rear panel mods, also known as the I/O & Overdrive kit, is the part that I started selling in July 2008. This is a subset of the Full kit. Hence, the kit is available as a Full kit or the Full kit upgrade for those who already have the Rear kit and just want to add the top panel mods. The general look of the kit is white on black accented by red & blue LED’s. The final overlay is still being test printed and has not been ordered yet, but will be very similar to the rendering in the picture shown.

This is not a simple mod package, it is a very extensive addition to the x0xb0x. The kit build is medium difficulty. If you built your x0xb0x you should be able to install the kit. If you want to get a general idea of the difficulty of the project you can download the Install Manual for the Rear kit here [9.16M PDF].

All the controls on the mod can be zeroed to return the x0xb0x to stock. The kit uses only high quality parts from Alpha, Bourns, C&K, E-Switch, Nichicon, NKK, Rean etc.. and includes everything necessary to build and install the mod:

* new rear panel pcb (sits above x0xb0x I/O board)
* new top panel pcb (sits above x0xb0x mainboard)
* new aluminum rear panel
* new machined aluminum top panel
* new overlays for the rear and top panels
* all parts needed to complete the mod
* all necessary wire & cable
* all necessary hardware to install the pcb’s and reassemble the x0xb0x.
* Install manual with step-by-step instructions for stuffing the pcb’s and installing the kit.

The new features are:
