ScaleGen - the ultimate scale generator and editor! Generate and manipulate musical scales in any way you can imagine. You think you know what a scale is - think again. In ScaleGen you can do all that you would traditionally imagine when it comes to scales and pitch organisation, and then much, much more. Define or change scales in the most detailed and intricate way. Audition the scales you make from within the app or export it as a MIDI file or to our app Gestrument - the revolutionary gesture-instrument. This is the tool for anyone who wants to go beyond the traditional tonalities in whichever genre. ScaleGen comes with predefined scales of all kinds - from the traditional western scales and early music (Baroque/Renaissance) scales to asian scales from India, Indonesia and elsewhere as well as more conceptual scales based in the classical contemporary music. This is the ultimate tool for experimental composers in any genre as well as for musicians who want to explore new ways of thinking about music. The educational aspects of how pitches can be organised makes ScaleGen a must have for serious music students. But the directness of the app makes the learning both fun and artistically developing. What is a scale? For most people it is a collection of pitches within one octave, with equal temperament (all half tone steps equally long) or with microtonal intonation. That kind of scales are of course possible to make and edit in ScaleGen which gives you a keyboard with complete control of up to 24 pitches within one octave. But the most interesting things with ScaleGen is when you start to think of a scale as something more open. Consider these questions: What if your scale was different in every octave? Why must a scale always go from down to up? What if you could use a variation of the overtone series as a scale? How does it sound if you divide the octave in five steps instead of twelve? In ScaleGen we define a scale as any list of MIDI pitches that you can manipulate in many ways. You can start with a keyboard to input pitches, you can use the concept of the overtone series with multiplication of frequencies, you can define the number and size of the steps in the scale or you can import MIDI files and use them as scales. Then you can fine-tune your scale in a matrix with a number of tools. You can then try and play your scale directly in the app, using built-in sounds or control your favorite external synthesizer/app through MIDI. If you want to try and play on your newly created scales in another way we recommend you open them in the app Gestrument - the revolutionary gesture-instrument. But you can also save the scales as text, Scala, or MIDI files and open them in another program.

FuzzWah - Vintage Fuzz & Auto-Wah Plugin (AUv3) FuzzWah is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic Pro or GarageBand. Overview FuzzWah combines two classic effects in one plugin that can be used independently or in series. The fuzz box and wah-wah pedal were among the earliest guitar effects pedals and remain very popular to this day. While I think FuzzWah does work great with guitar, it can also produce interesting results on pretty much anything from drums, synths and even vocals. FuzzWah wasn't designed to be a clones or models of specific hardware effects, but it does draw inspiration from those classic units from the 1960's and 70's, then adds a few extra features. The fuzz section includes an optional "Vintage" mode for a rounder warmer tone, and a Skew option for dialling in that classic gnarly fuzz "ripping" sound. The wah section adds 4 selectable frequency ranges, and an "Auto" (envelope-follower) mode for funky filter auto-wah effects! FuzzWah also includes a simple "set it / forget it" noise gate to keep your signal nice and clean. Signal Chain & Amp Sims The order of signal processing is as follows: IN -> Noise Gate -> Wah -> Fuzz -> OUT You can drive the Fuzz section harder using the Wah Boost parameter. Much like in the real world, I think fuzzes sound best when going into slightly driven amps, rather than into something pristine and clean. Of course, that's entirely up to you, depending on the sound you want, but my personal favourite amp sim combo is FuzzWah going into ANALOGyAMP.

Verdict
The clearest difference is review sentiment: FuzzWah at 100% against ScaleGen's 71%. FuzzWah also leads on price ($1.99 vs $3.99) and device support (4 vs 1). ScaleGen's advantage is rating (4.7 vs 4.5) and ratings volume (12 vs 2). On ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
ScaleGen costs $3.99 and FuzzWah $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
ScaleGen holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: ScaleGen has 12 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 71% of ScaleGen's written reviews are positive against 100% of FuzzWah's, so the app with the better star average is not the one people write more warmly about.
