Mugician Review in Japanese

I had a few brief conversations with this guy when he gave me feedback about what he thought needed fixing in Mugician, but he seemed to like it:


I ran the external text though Google translate, but can't translate the text in the video. Can anybody give me a gist for the Mugician review (last review where he is playing it)?

Mugician Pro work started

As a start, I am modifying current Mugician code to be "Mugician Pro". I got some issue that's keeping the store version of Mugician from cleanly installing "Mugician Pro" at the same time.

The first thing I am adding is some FM synthesis capability - to give a much warmer and tweakable underlying tone before it mashes through the distortion. Since space is so scarce, I am taking the whole bottom row for sliders. Interestingly, no range is lost since the leftmost item on first row above the controls is already the lowest note. You only give up having an alternate fingering for the bottom 5 bass notes in that case; a tradeoff I could see coming.

Anyway, the plan is to at least put up Mugician Pro as a bug-fix branch of the free version with enough new features as would be commonly useful. I do plan on keeping this instrument simple.

I am not going to get into the game of trying to entice people to buy with more complexity. Every wierd new feature will only be used by a small number of purchasers, and I will end up with a big ball of goo trying to rope a lot of people by catering to all of them. You may note that there is not a single letter of text in this app. When I really have to put that first one on, I have failed in simplicity.

The link below is entertaining for sure. But look beyond the entertainment aspect of what he is doing for a moment and think about it seriously. A wearable iPad mount that can host external effects and a wireless out is a VERY GOOD THING:

Mugician Tutorial

Demo video using the older 1.0 Mugician. It shows off the kind of new music (microtonal metal) that becomes possible with Mugician:


Send me links of you playing better than me. I think I can make free Mugician work as long as I can keep the more skilled players coming back, willing to pay for a version with specific tweaks and enhancements that they need to advance.

New Strategy

I am confident that this form-factor is the most practical layout for an iPad instrument, and one of the few that makes fretless music reasonably easy. There will be multiple instruments that pick up this form factor in the future - it's the only thing that really works with the iPad in terms of ergonomics. I am going to let this version go free until I can figure out how to drive demand - and possibly post a "pro" version (that gets updates) for the people that want to support my efforts with purchases.

Idea: Most people have the free version, post videos of their skills. The more dedicated players might be buying more advanced Mugician-like instruments - like a +10 skill mad broadsword...

I float around #100 (10/day) in music with any price, but hit #4 (2000/day) while it was free; so maybe building a community around this blog and youtube will work. The distribution is exponentially clustered around the top, so being at #100 seems kind of pointless.

The plan is to attempt to aggregate videos of people playing this instrument, getting better as more people practice it. To build a community around this kind of instrument - which could end up being a different app which is similar.

Mugician Microtonal Technique

There isn't one specific thing about Mugician that makes it special or unique. But what does work well is a combination of things:

  • Keep latency low at all costs. An instrument with perceptible latency is most likely useless to a skilled musician.
  • Go fretless, and put up with the initial learning curve that it imposes. If I cave in to requests to make it snap (ie: autotune) to notes, then I am suddenly back to something that sounds too electronic. At that point, everybody want's a post-processor to "humanize" the tone. It also takes away what is superior to this layout: microtonal things that are readily available to singers and violinists - in a keyboard-ish layout.
  • Make the spots for a finger about the size of a finger, so that you can play fast. This makes two-handed finger-tapping technique work really well.
  • Use the time-honored guitar (fourths) layout, rather than the piano layout. There is precedent for this inside and outside the app store, btw.
  • Make the instrument as stateless as possible. You don't want to be going crazy in a solo and have everything blank out on you with a window that you need to close.
  • A practical, flexible sound. If you are a working musician, especially a metal musician, then flexible distortion and reverb are going to be the cornerstone of your sound. I didn't go the route of sin/saw/tri/square waves. That is stuff that is done mainly because it was easy in hardware; not so much because it sounded better than overdriven tube amps. I didn't go the route of samples either, because they end up being too specific; leading you to needing a gui with a librarary of discrete samples to choose from, and no continuous blending of them.
  • All change is continuous, from voicing to expression and fretlessness.
What can you do with Mugician that you won't be doing with your guitar any time soon? Microtonal scales! The emergence of touch computers will reverse the auto-tune trend within a few years; because it will change the instruments that people play on. Progressive music has already gone down the path of everything you can do with 12 tones, the most bizarre time signatures you can count, and will be exploring this too.

This is a video that I quickly hacked up in order to show the latest version of Mugician to a reviewer. I am kind of out of practice as a musician. I presume there are a lot of people that can do better than my demo playing. But here is a clip:


You will notice in the video that usually when I put a finger down, the note turns Green. That color is used for when you play "in-tune" with the nearest semi-tone. When you see red dots, that is when it is "out-of-tune" with the nearest semi-tones. These are not necessarily mistakes, but important tones to have.

When sound is viewed in terms of physics, the black and white keys are actually out of tune by any reasonable definition of what the tones should be. Vibrating bodies have overtones that are integer ratios to the fundamental tone. Most microtonal systems adjust the fourths and fifths to be perfect, so they don't match piano. Just intonation tries to place notes such that there are small integer ratios - an effect similar to what you hear when playing around with analog electronics. They can be somewhat close to the standard tones, but they can't exactly match because the 12 tone system is a completely artificial approximation of the physics behind the sound.

Microtonal music, which was typically formulated before the 12 tone system, therefore usually features such tones. Middle Eastern music is the most obvious place to find practical uses for quartertones, where notes are in between what would normally be the black and white keys. In a lot of ways, heavy metal is a bad imitation of these scales, crippled by the fact that they are playing guitars with frets on them.


This isn't the only example of microtonal music, but to be sure, this is where you should start if you want to learn how it usually arises in practice. It mostly boils down to when you play a minor scale, you stretch the third and sixth interval to be ambiguous between major and minor. The core pentatonic scale is still there; but now there is a note exactly half-way in between its wide intervals. When you play in a style with a lot of accidentals, using these in the right places gives you options you never have on any fretted instrument.

My hope for Mugician is to help break open new music genres, and take fretless metal ensembles into the mainstream. The more an instrument does for you, the less you can hope to become really good at it. If you can't play out of tune, then that's one dimension of your personality that disappears; ditto for fixing your rhythm. By the time the computer fixes everything, you can't tell who is who by ear alone.
