    just tried Fugue into SPA, yes great fun that :)

    Have you only been able to do this with AB3?

    No but it's a lot easier to do that now without thinking about it. Just put fugue as sender and spa as filter and I put Animoog as receiver and you can save it all as a preset.

    How can we tell which apps support multiple instances like the Midiflow for AB3 stuff vs StepPolyArp which doesn't? Are the multiple instance versions secretly AU behind the scenes?

    No. These are a special Audiobus feature.

    Before purchase? I think only from the app description.

    Would be great if it were possible to filter those here https://audiob.us/apps/midi/capability/ab3

    @Processaurus enlighten me about your notes programming when you can :)

    I wish there was an app like StepPolyArp available for iPhones..... :neutral:

    So what exactly is, um, a midifilter?

    Think of MIDI as a stream of numbers that provide instructions to apps and hardware for how you want to do things. MIDI filters allow you to take a MIDI stream and only allow MIDI through that is appropriate for a particular app or hardware. Examples would be only allowing certain MIDI channels, notes, CC, or velocity. In this way the same MIDI stream can be used for multiple apps or hardware.

  • CarnbotCarnbot

    SPA can also be used as a simple scale filter if you turn off the arp button. I hope ScaleGen gets the AB3 treatment too.

  • AudiojunkieAudiojunkie

    I keep hoping and dreaming for an iPhone version of this app..... :neutral:

    I guess it's because Troublemaker's arp is so damn cool, I never thought about using StepPolyArp with Troublemaker. Then last night the idea came to me in my sleep (no joke).

    Sooooo awesome! External or AB3 midi keyboard in the midi input slot, SPA in the FX slot, Troublemaker AU in the output. Set up the scale and arp you want, set latch in SPA, hit keys, and have your acid bass lines change within scale!

    This is an answer for all those who have wanted scales in the Troublemaker step sequencer, and it's a beautiful thing! B) <3

    [edit] BTW, hold down the "Modulation" button in SPA to set the MIDI cc of choice for something like the filter or resonance, and tweak to taste!

    I spoke with the dev of SPA, and he said the app update originally had the multiple channel routing, but by AB request (the plot thickens), that was replaced by the single channel icon that is displayed.

    If you still need the multi-channel functionality, SPA can still be used in that way as an Audio AB slot, not a MIDI AB slot

    Seems like it could work like MidiLFOs does, where there are four MIDI outs. You just load up each single out in a separate midi input channel, then route as you want. I wonder why that isn't possible / allowed?

    But, like you say, you can still load it the old fashioned way and it will work just as it used to.

    How MIDI works in AB3 pipelines is more clear now; the Midiflow apps and Fugue Machine can exist as multiple instances not because they are AUs (they are not), but because they implement and expose multiple MIDI ports.

    This means that apps like StepPolyArp and Cream need to let the user select different MIDI ports per row (for SPA), instead of different channels for the output. That should be doable, but the fact that SPA has not done so, yet still updated for AB3, is perhaps a sign that going from channels to multiple ports has other consequences? I hope not, because then the AB3 MIDI framework would be great for easy and quick setups (their expressed desire, fair enough), but unfortunately not for more involved MIDI handling. I'm hoping the latter can also find its way as a standard for AB3 apps, like we see with Fugue Machine.

    (AUs can't send MIDI with Apple's current limitations, so no need to wish for SPA becoming an AU yet - I take that back)

    I don't get why multiple pipelines ? Surely if an app has multiple pipelines, it is the same as having a single port with multiple channels. Why change the terminology that has been used and understood by many many people for many many years ?

    I was really surprised how old the app was, I must have just tuned the recommendations out over the years.

    Or maybe it came to my attention at exactly the right time for me to see it as part of my workflow.

    I prefer to let the universe drive so will go with the latter.

    Slam in into an AB3 input slot, chuck some MIDI effects onto it and route to whatever takes my fancy.

    Same with Oscilab driving the MIDI effects (outside of AB3 though), constrain to a scale, randomise a bit, route to various synths and let the music make itself.

    I then noodle over the top with either my hamfisted keyboard skills driving a synth or my, slightly more competent, guitar work through Bias/Tonestack sometimes layering up with MIDI Guitar driving some random synth.

    What I like about SPA is the fact I can get something musical going really quickly and then build on subtle variations of it.

    I suspect that without AB3 and the MIDI effects bundle SPA would have just passed me by. I guess the combo really just fits my mix and match approach to music creation.

    As mentioned in another thread, I haven't opened Gadget up since the big update, I'm just having too much fun wiring stuff together in a more loosely-coupled environment.

    Not to say Gadget isn't great, it's just not for me right now.

    Hey, I just realized Midi Splitter can be used to overcome the single port limitation in SPA ... sort of. No time to explain in detail, but here's a preset if you want to see what I mean. Load the preset and then play an E1 so SPA.

    Audiobus preset 'SPA MIdi Split': http://preset.audiob.us/avf4Zot1O8yhtV6

    Sorry, no time now to help out if it doesn't work ... ymmv

  • bleepbleep

    I guess one reason why SPA has slipped the radar of so many, is that it never ever goes on sale.

    Could be, and it's gone up recently for U.K. buyers so not particularly cheap. I think I got sidetracked by ModStep, which did go on sale recently.

    I have just had Cubasis as midi input and output with the Randomizer in between, you need to use 2 midi channels in Cubasis, one for your programmed part, and the other to record onto.

    I will do this with modstep a lot when it works :)
