FAQ

General

Are Oscillator Devices products compatible with my MIDI controller?

Oscillator Devices products comply with the MIDI 1.0 standard and are therefore compatible with all common MIDI controllers. All MIDI inputs are isolated.

Which MIDI cable do I need and what is the pin assignment of the Mini-TRS MIDI sockets?

All Oscillator Devices products with Mini-TRS MIDI sockets are assigned according to MIDI TRS type A. This is the official MIDI standard for MIDI TRS. (See also https://minimidi.world). You can find some 5-Pin DIN to MIDI TRS MIDI cables in the shop, MIDI TRS cables made by or for Boss will also work (e.g. BMIDI-1-35 or BMIDI-5-35).

What is the latency on the MIDI Thru port?

Prior to 2024 all Oscillator Devices products had software MIDI Thru with a latency between one and two characters (approx. 0.5 ms). From the end of 2023 all products are changed to a latency-free MIDI thru scheme.

I have special requirements, like custom CC messages, can you do that?

Yes, defnitely! Just get in touch. Change the MIDI CC number, to avoid collisions and save MIDI channels, for example, is no problem.

Are there firmware updates available?

As of now, all devices except Garbage Collector Mini and the Imps/Goblins are able to receive firmware updates via MIDI.

Firmware updates, once available, are performed via the WebMIDI interface.


Orders and Shipping

I want to add items to an already existing order. How can I do that?

If your order has not yet been shipped, you can simply place a new order and select “Add to existing order” as the shipping method. To avoid mix ups, enter your order number in the order notes during the checkout process.

Here are the most common reasons why installation is not possible:

  • No room: The most common reason is lack of space. In addition, installation in housings smaller than 1590B is rarely possible.
  • The 3PDT switch is used to attach parts of the effect board and can therefore not be replaced. It’s possible to fasten the board with separate standoffs, but this is very time-consuming and is only worthwhile in the rarest of cases.
  • Special switches: Some manufacturers use switches with special functions, e.g. TC Electronics. Installation is usually not possible here.

I want to upgrade effects device XYZ, which version of the MIDI upgrade do I need?

That’s easy:

  1. Does the effects device have one or more switches that you want to operate? Single switch = Imp, Multiple switches or special functions = Goblin.
  2. Does the effects device have one or more 3PDT true bypass switches? Then you need the 3PDT variant (Imp-3PDT, Goblin-3PDT).

I read the installation manual but I’m still completely lost. What can I do?

For that case there is an addition to the installation manual that explains concepts, measurements and the configuration in detail. Also, for the Goblin-SPST and the Goblin-EXP exist detailed explanations which can also be useful for other pedals. Finally there are installation videos for the Imp-SPST and the Imp-3PDT.

I am a manufacturer of effects devices and would like to integrate MIDI functionality into my products. Is there a version that is suitable for this?

The Goblin-3PDT is ideal for this because its connections are arranged in a 2.54 mm grid and therefore suitable for conventional pin header. Because of that there is no wiring, the Goblin-3PDT is simply plugged onto the circuit board.

I am a manufacturer of effects devices and would like to integrate MIDI functionality into my products, but would like to design my own hardware. Is that possible?

Yes, it is possible to only order the preprogrammed microcontroller. Hardware design support and commissioning support included.

I want to use multiple Imp-3PDTs in a pedal. Can they be daisy chained?

No, unfortunately not. To save space, the second series Imps have no outgoing MIDI signals. But you can use the Imp-THRU, a small 4-way MIDI splitter, that fits into the pedal to connect up to four Imps.

Can the Imp-THRU be used to build a MIDI Thru box?

Yes, absolutely. You only need the Imp-Thru und four sockets. Wire them up and you have a 4 to 1 MIDI Thru box. Best is, you can wire the outputs for specific brands, like Strymon or Chase Bliss.

Can the Goblin-SPST also handle the PitchFork+?

The regular PitchFork can be controlled entirely with its knobs and switches. The PitchFork+ on the other hand uses a menu. So, the PitchFork+ can be controlled like any other pedal in controlling switches, EXP and EXT, but cannot use any of the special functions of the regular PitchFork.


Garbage Collector/Trash Panda

Can the Garbage Collector also be used as a channel switch on my amp?

Yes. But be careful with the voltage levels. With modern amps it should be no problem. As long as +5V are not exceeded there are no problems.
Vintage Amps on the other hand often have AC with more than 5V on the channel switch. For that there is a switch for every port on the inside of the Garbage Collector, to disable the expression function and disconnect GND from the Jack. Then the port is able to switch +-60V.

Is the Garbage Collector/Trash Panda compatible with each expression input?

The Garbage Collector and Trash Panda are compatible with almost every expression input. The exception are expression inputs with more than 5V, which are very rare. The ones that I encountered mentioned explicitly that only a specifically made expression pedal might be used. These can be made to fit, though, with specifically made converters. Get in touch.

Volume/Boost pedals often have problems with digital potentiometers like in the Trash Panda, Garbage Collector and anything else that splits expression, automates expression or turns MIDI into expression. While they work in principle, there are audible steps when slowly sweeping from one position to another one.

Is the Garbage Collector/Trash Panda compatible with Line6 products?

Line6 uses a special wiring scheme for their expression inputs that differs from regular expression inputs. These allow for connecting two expression pedals via a TRS sockets. These are not compatible with regular TRS expression pedals. But, with a special cable or adapter they work with the Garbage Collector/Trash Panda. If you’re interested, get in touch and we can make you a cable.


Minerva

Is the Minerva polyphonic?

The Minerva is monophonic. Whenever you play a new track, the already playing track is stopped. There are plans to make a new Minerva that is polyphonic, but probably not before 2026.
