Want to plug your guitar into an iPad so you can carry around a giant pedalboard in your pocket virtually? You’ll need an interface of some sort. When I started this journey, I thought I had done my due diligence, as I thought that this stuff was at least on par with the hobby level electronics for the desktop.
Most of it isn’t.
The community doesn’t expect it to be and the manufacturers don’t for the most part seem to care about real world performance. I am going to try to make the guide I wish I had when I started this, and hopefully it will help you avoid mistakes and pitfalls I fell prey to. I thought I had read all the necessary “reviews” when I started this, as there were even web pages devoted to this subject. Some of them were obvious nonsense, but some seemed well intentioned. I made too many assumptions that these sites would have screamed from the hills if the very basics were broken, but I was wrong. Really wrong. I intend for this to be actually useful to using the devices for their intended purposes.
I will add devices as I receive units to test. For manufacturers, most of you already know from our time together on desktop devices that I will most happily accept products for review, and in that case, I will submit my findings to you before posting so you have a chance to comment or set me straight on any issues I have, but as always, I WILL report the truth as I see it. I welcome your participation, but I want to reiterate the risk you are taking that I may give your product a bad review.
TL;DR – here we go.
I tried to get a really good look at these things to see basically what sorts of ins and outs they have…Even pictures are a bit difficult to track down sometimes, and most of the questions you would think to ask when looking for this sort of thing aren’t really available. Contacting the manufacturers was sometimes helpful in clarifying things.
Apogee’s Jam line of products seem like they would have been cool back before the lightning audio days. As far as I can tell, they don’t have any actual outputs, instead relying on the mobile device to provide the audio output. I think this is a non starter for our purposes, and won’t be saying any more about these as far as I know.
Verdict: No thanks

Apogee is an enigma, they were really early to jump into the digital game, when there were still significant (and actually audible) problems with digital recording. We got their early filters for our Mitsubishi ProDigi format machines and it was a difference we could not only measure, but made a big difference in typical day to day stuff like setting compressor thresholds. That bit of splat, that I think George Massenburg assured us was group delay, made compressors for instance react to a different level than the one we apparently heard. Technobabble aside, it was a huge improvement. Later we would go on to get their analog to digital converters to replace the front end of the early tape based digital machines like our Sony PCM3348’s and later as front ends to the Modular Digital Multitracks (ADATs and DA-88’s for instance). They took a lot of first steps and really worked out how ADCs and DACs would work in a multitrack environment.
