Examples of how I use Metric Halo MIO 2d +DSP guitar processing

I finally got around to recording some examples of what I’m doing with the MIO 2d +DSP amp simulations and effects. Note that these are totally geared towards the music I’m currently playing (alternative pop-rock) and I thus didn’t try to get other types of sounds out of it.

All the sounds are totally done by the MIO 2d +DSP except for the longer stereo delays which require too much memory and are frankly easier to setup through AudioUnit plugins with host tempo sync. One thing to realize is the the 2d amps and cabinets have no parameters at all. You use the already existing MIO +DSP capabilities (MIOStrip, compressor, EQ, character, volume, …) to sculpt your sound, this is totally different from other in-the-box guitar amp simulations. However, it now does make a lot of sense to me and it gives a lot of flexibility. The phaser, flanging and chorus effects are all built by me using 2d +DSP graphs, based on examples I found around the web. I also built a tape echo simulation for one song this way that I really like.

I use Bidule to tie everything together and basically create a dedicated MIO mixer snapshot for each song which I save as an AudioUnit preset. These are loaded by Bidule when I press the appropriate switch on my foot pedal. Within each MIO mixer I have several channels with different sounds and have the volume pedal hooked up to control the guitar volume. Using the Mackie MCU MIDI support of the MIO mixer and send out the required MIDI messages to raise or lower the volume of each channel.

I’ve got a mono firewire send setup to go to Bidule where I use a Peterson Strobosoft tuner plugin as well as FabFilter Timeless for the delays and Guitar Rig 3 for more esoteric psychedelic delays. I route the stereo wet signal from Timeless and Guitar Rig back to the MIO mixer through firewire returns and mix it with the zero-latency 2d +DSP sound. This gives me a very responsive main guitar sound and some latency (64 samples in Bidule) for the delay, but it really makes no difference since that sound is delayed already anyway :-)

As far as hardware is concerned, I use the ULN-8’s DI for converting the guitar signal to digital and then send this over AES to my 2882 which is totally dedicated to the guitar sound. The processed guitar sound is sent back over stereo AES to the ULN-8 to create an in-ear mix for the band and to do FOH when we’re playing small gigs, but I also output a stereo analog signal on the 2882 for larger stages where the FOH is done by a dedicated team.

So here are the tracks, the steps in brackets are the ones I optionally turn on with my foot pedal.

  6. SoftSat Character -> MH Clean Tweed (-> +DSP Tape Echo Graph) (-> Guitar Rig Psychedelay) -> Timeless Delay -> Haloverb
    MIO Guitar processing 06 – Dry

  9. Modern Tube Mic Soft Sat Character -> MIOStrip -> British Mil Spec Light Grind -> MIOStrip (-> MIOVolume) -> Timeless Delay -> +DSP Diffuse Prime Verb
    MIO Guitar processing 09 – Dry
    MIO Guitar processing 09 – Wet
  10. FET Character -> MIOStrip -> British Mil Spec Rhythm -> MIOStrip (-> Timeless Delay)
    MIO Guitar processing 10 – Dry
    MIO Guitar processing 10 – Wet

Hope this helps those who are curious about the MIO 2d +DSP guitar capabilities.

PS.: these are all parts of songs from my band Flytecase, if you want to hear more, feel free to visit:, note that the recordings there were not yet using the +DSP guitar simulations.

    really nice patches. And thanks for sharing the ideas with your several channels for different guitar effects. Love to see more on how you set up the mulitbuss mixer you linked the list :

    Hi, thanks for the compliment! Next on my list is indeed to go step-by-step through the MIO console setup that I use for my guitar sounds. Stay tuned!
