ZPI Forum / The vault: old video demos
« on: July 27, 2018, 08:54:48 PM »
Here, I'll put up links to videos showing demos of early hardware prototypes.

Note: the earliest prototype had a built-in touchscreen interface and included a low frequency oscillator (LFO.)  These are not included in the current version.

Here, I'll put up links to older videos showing demos of previous firmware versions, starting with the early 2017 pre-production prototype overview.

In general, anything shown in these videos also applies to the latest (May 2018) version.  The latest version does lots more than is shown here!  This will be documented bit by bit in the ZPI Overview videos.

ZPI introduction - Part 1 (May 2018 firmware)

This is an overview of the hardware with a simple footswitch program applied.   
(Footswitch programming is very flexible and easily changed.)

(Duration: 3m16s)


This is an introduction to the Zoom Pedal Interface which is a usb midi floor controller.  It can be used as a general purpose controller, but it’s optimised for Zoom pedals – the G5,G3.G3x, B3, the MS-50g, MS-60b, MS-70cdr and the b1on and g1on and the X versions of those.
Here I have a 12 switch controller.  With the latest hardware improvements, there is an LED as well for every switch.  If you already have a base unit, don’t worry, it still will work with the new add-on units.

As before, there are 4 expression pedal jacks, 3 usb ports (and if more usb ports are needed, a usb hub can be used) and an ethernet interface.
I have an ms50g and an ms60b connected, so it’s driving 2 pedals, but we easily could drive more if needed
There is wireless built in and I’ve already connected to a laptop running a vnc viewer and in part 2 I’ll start looking at the user interface.

The footswitches are programmed quite simply at the moment.  There is a master tap tempo switch that automatically has its LED flashing at tempo; 

a momentary tuner switch which turns on the tuner of both pedals when down.

The other upper switches turn on or off the 4 effect positions in the ms60b chain and the lower switches control the 6 effects of the 50g, with the LEDs indicating whether each effect is on or off.

Both pedals are displaying the first effect in their chain, so you can see the effect of the footswitches on that effect, and how the LED follows the state of that effect.  Similarly, even though you can’t see it, the other effects in the chain are being turned on and off by the other footswitches.

This is a very simple example of footswitch programming – very simple to do – and if you want to, you can make some very intricate mappings that do multiple things, you can program both press and release, and you can program to cycle through actions with successive presses.  This is completely flexible and can be changed at any time by loading a different footswitch mapping – you can define a map, save it and recall it, including by using a footswitch.
There are no limits to the number of maps or to the number of actions a footswitch can perform.

Let’s go to the laptop.  In part 2 I’ll go to a screen capture and start looking at the user interface

The Zoom Pedal Interface (ZPI) is a MIDI floor controller optimised for use with Zoom multi-effects pedals, but able to control any other MIDI controllable pedal (or DAW) in the same way as any other MIDI floor controller.
(Well, not quite the same way... the ZPI aims to provide a graphical user interface for each connected pedal, to make MIDI control as simple and intuitive as possible, without really having to know much about MIDI.)

The permissions in the ZPI forums will allow any Zoom patch exchange member to post replies.
(So, by logging in you will be able to ask questions or make comment on existing posts.)

ZPI owners will be able to start new topics - please contact me to arrange this if you are a ZPI owner.

This area will grow to include documentation, programming examples, answers to questions, etc, etc.    To try to keep it logical, posts/questions etc might be reorganised as time goes on.

First posts will be pinned: an overview information post, some links to youtube videos and a dedicated post for any questions you want to ask.

Significant announcements will also be made on the ZPI facebook page:

Questions?  Please ask!  (In the Questions topic! But please read the information posts/watch the (short) videos first!)

This is the latest Zoom Pedal Interface information sheet (last updated 25 July 2018)

The ZPI is a MIDI floor controller able to control any MIDI capable pedal, but optimised for control of the following Zoom multi-effects pedals:

G5   G3   G3X    B3
MS-70CDR      MS-50G   MS-60B
G1on     G1Xon   B1on     B1Xon

Video demos:

Click here for up to date overview videos.

(Click here for older videos.)

How does it work?
The ZPI uses MIDI commands via the USB port for all control.  No Zoom pedal modifications are needed.  The built-in footswitches can be programmed to perform any combination of control commands.  Expression pedal inputs can be assigned to control any continuous (dial or slider) parameters (not just those that Zoom decided could be controlled!) allowing some interesting effect variations.

How many switches/LEDs/expression pedals?
The ZPI base unit provides a 4+4 configuration (4 footswitches + 4 LEDs,) and 4 expression pedal inputs.  Each expression pedal input can be assigned to any number of effect parameter dial or slider controls.
An expansion unit adds another 4 footswitches + 4 LEDs.  Two expansion units can be added to make a total of 12 footswitches + 12 LEDs,

What can be controlled?
Almost everything on the Zoom pedals listed above can be controlled via USB: 
    • patch changes,
    • effect type for each position,
    • effect on/off setting,
    • effect parameter settings,
    • tuner control (except G3, G3X, G5),
    • tempo setting (except as below) which allows master tempo control,
    • signal direction (G3/5, B3 pedals)
Any of these (or combination of these) can be assigned to a footswitch.

What can not be controlled with the ZPI?
The following can’t be controlled because the Zoom pedals don’t allow it:
    • Tempo setting for series 1 pedals – G1on, G1Xon, B1on, B1Xon.  (For these pedals, tempo is read only – note though that they can act as master tempo source.)
    • Tuner control for G5, G3X and G3 (v2) pedals
    • Looper control
    • Master (or Global) settings such as battery type, display contrast, power management, tuner/tap selection for MS pedals, auto save setting, master volume for some pedals.  (On some pedals, these can be read but are not displayed by the ZPI at present.)
    • Signal flow direction on MS and 1 series pedals.  (The ZPI display changes but the direction on the Zoom pedals does not change.)
The following can be controlled but are not as yet by the ZPI:
    • Display scroll position (for pedals with more effect slots than displays).  The ZPI shows which effects appear on the Zoom display(s)  (Controlling this is possible and could be a future enhancement.)
    • Assignment of the Zoom “Control in” pedal/switch (or inbuilt expression pedal.)  This is possible to show and control and could be a future enhancement.  (Note: this includes the G5 “Custom” Z-pedal effect assignments.)
    • Deleting or inserting effects, changing effect position in the effects chain.  (Future.)

In addition, please note that some changes can be made only by reloading the entire patch information.  Any such change thus has the same effect as changing a patch – eg, loss of tails.  (This also makes these changes unsuitable for assignment to an expression pedal, as rapid changes will overload the USB channel and/or the Zoom pedal’s processor.)
These changes are:
    • MS series pedals: tempo change; any change to effects in slots 4, 5 or 6
    • 1 series pedals: volume change, effect type change

How does the display work?
The ZPI uses standard  VNC (Virtual Network Computing) technology to provide a remote display on your Android, iOS, MacOS, Windows or Linux device.  This requires a VNC client program on your device.  There are many of these available at low or no cost:  TightVNC, RealVNC, AndroidVNC have been tested and work with the ZPI.   The ZPI interface has 3 different “dial” modes to work best with different VNC clients and input devices (touchscreen, mouse.)
The ZPI provides a wireless Access Point to connect your device (and also an ethernet port which can be connected to a router for VNC connection via your local area network.)
Note that the ZPI also can connect by cable to a standard HDMI display or television, with a standard USB mouse (and keyboard) for input.

Does the ZPI have other MIDI capabilities?
Yes it does. 
    • The ZPI will accept MIDI via the USB port (using a MIDI to USB converter if a standard 5 pin MIDI interface is needed) and can translate PC, CC and note on/off messages to control pedals attached to the ZPI. 
    • The micro-USB OTG port provides a class-compliant MIDI controller interface which can connect to a DAW (eg: Ableton Lite), allowing the DAW to control the Zoom pedal(s). 
    • MIDI real-time clock input can be used to set master tempo.
    • The ZPI can use MIDI controller input to vary effect parameters in the same way as expression pedal inputs.
    • ZPI footswitches can be programmed to send (/receive) MIDI commands to (/from) a DAW or any MIDI capable pedal (using a MIDI to USB converter if a standard 5 pin MIDI interface is needed).

Basic unit:       US$187
Expansion units:    US$49

ZoomLib: General discussion / Forum restructure
« on: February 24, 2018, 06:57:16 AM »

You'll notice that the patch files have been moved.  This is an attempt to reduce the hosting resources being used by the forum, which are becoming an issue. 
Please let me know if there are any problems.

ZoomLib: General discussion / Having trouble registering?
« on: February 02, 2018, 06:40:19 PM »
To try to discourage spammers, registration includes a couple of questions that spam peddlars might have trouble with.

(If you're a spam/spam/spam/etc peddlar, please stop reading now.)

Occasionally, legitimate users have difficulty too.  For those, here are the answers: "guitar" and "japan"
(You still have to work out which question each answer is for though!)


Edit:  That's a bit funny:  I've also included a spam filter that changes certain words (v i a g r a, p r e d n i s o n e, etc) to the word "spam" - you can see the effect above.
