I returned to this project after a haitus and more learning and while it has become much, much more streamlined and higher headed (:---) it is still having the same issues running inside MobMuPlat: garbled sound.

If you have or can make the time, please, have a look at it, and tell me how I can resolve this problem, as I think it would of benefit to the world-at-large, thru the guitarists in the world, and as there are so few guitar apps, for Android.

It has a simple master patch, largely based on the "Router", into which all of the pedals (16) have been embedded.

And taking whale's (?) advise I added switch~'s to all the pedals so dsp only turns on when they are activated.

The first (MobMuPlat) page is the "rack", TiGR=The (i) Guitar Rack, which each pedal being on a subsequent page (swipe at the top) (note: currently "Presets" and "Record" do not do anything).

The hardware I am using which may be the issue is a Motorola Moto E (2nd Generation) with 4G LTE, Android 5.1, Kernel 3.10.

And I can't tell if it is my hardware's problem or libpd is just not up to the task to handle the load.

Instructions:

You select the pedal from the first page (the sliders, so you can stack multiples of the same pedal)
And
Each page has it's own settings/controls and a bypass.

(Note: more "slots" could be added, if 6 is not enough , by just adding sliders and Routers.)

I thank you so very, very much in advance for any advise you can offer.

Maybe if enough of us chime in we can get this (free) into the hands of all those guitarist who do not have enough supplementary income to spend on a rack.

p.s. as to credits, it depends on a lot of other people's work. To name a few, Guitar Extended, hardoff's DYI2 library, tb_compressor, etc., etc.

And to them I say: "Thank You. It is so wonderful to walk on the shoulders of giants who are so kind, generous, and loving. -Peace"

Have you tried it on other hardware? The Moto E is an inexpensive phone. I've tested your patch on a Nexus 6 running Lollipop and a Nexus 7 (2013) running Marshmallow, and it seems to work fine on both.

You might try changing the sampling rate down to 32000 or 22050 and see if you have enough processing power for that.

In my experience, another big issue (for Android) is latency, the Nexus' latency is not great, perhaps the Moto is better?

have not used this but... maybe

another option is to use mmp as a controller only. and use your computer to do the processing of the audio.

@monkeyswarm, @0123456789_9876543210:

Thank you, both, for your suggestions.

It IS really good to know better harder eliminates its issues. So that is Great news!

On the down-side, dropping the rate did Not improve performance on my hardware, but trying the app on my son's (better android) the problem is solved.

So it appears power really is the issue.

And using superpowered wouldn't really work as it needs to stay "in-house" meaning as only a mobmuplat add-on with no additions, as that would scare users away.

And while I could use OSC to bypass the handheld entirely and reroute directly to the laptop (which I have done on other incarnations of this app (for personal use) and it worked great) it would undermine the primary requirement of the app:

Get a cool, effective, varied, and useful pedal app into the hands of those guitarists and/or instrumentalists who can not afford "traditional" pedals.

So, next steps:

I need to find out (and perhaps, The Community continuing to beta-test it for me will do the trick) the "Minimum System Requirements" and "Recommended System Requirements" levels.

Currently, I know it's above a Moto LTE (and i'll post back it's cpu speed later) and somewhere potentially below a Nexus 6. Which is really good information.

footnote: I am going to add a delay and a 4-tap to the chain (since it's needs a simple delay not just the hardoff spectral and Guitar Extended's spectral (come to think of it, it only needs one of those, so I'll drop the Guitar Extended one) and have decided with almost everyone probably adding the EQ5 and compressor to the stack, 4 is just not enough slots for additional effects, to add a 7th slider to the main page, bringing the total to 5+the (default-ish) 2.

This is probably going to throw (ah-huh!) Will throw our current knowledge off, so will post an update once I'm done.

Thanks, to both of you, and any and all who chime in on this, as I continue to remain convinced it IS a worthy cause and is a very effective solution to a challenging problem and one well worth pursuing.

2nd footnote:

I do not know how nor have the stamina/time/power/knowledge-base to pursue packaging it as an iphone or android .apk so I'd REALLY appreciate someone to volunteer to do that for us, so we can share in on the two stores/portals. I have NO desire to make ANY money on it and can't anyway given the licenses of the embedded effects. So this would be totally gratis. But VERY much appreciated.

Peace, love, and ever-changing joy,
