I really love Scaler and in general I find it very useful and creative tool for composition. However there are 2 areas where I might like to see improvements. The first is concerning the ease of finding a blues repertoire. I realise that this is challenging for the plug in because your Basic Blues chords do not necessarily come from one scale. Traditionally a Blues Pianist would be moving a Mixoloydian Scale to follow the changes so not sticking to one chord over an entire progression. therefore in Key C you would not find a C scale that would give you the Blues Chords of F7 or G7 naturally. So in Scaler I have to find these chords myself by going to Scales for C7 (C Mixo) , F7(F Mixo) and G7(G Mixo). Alternatively just the major scales of F , Bb and C. Once you have done this and made a grouping you can save it and move it to any Key. However you can also think about a Blues in C as a mixing of Major and minor parallel keys. So in C= C maj and C min. From this grouping you can make up both the Cmajor Blues Scale often referred to as the Country Blue Scale by Guitarists, and the C minor blues Scale again another scale very familiar to guitarists. the First C maj Blues Scale is usually C-D-Eb-E-G-A. The C min Blues Scale is usually C- Eb–F-F#-G-Bb. I think that these are 2 valid scales but neither of which seems to appear in Scaler which is disappointing at least from a guitarists point of view. It appears that there has been greater focus on , or that it has been constructed with pianists in mind. That’s not bad but I feel that this 2 scales should have been included since it is easy task to generate the essential or most common Blues Chords sets from these 2 scales. often in Blues music you find that 2 or more scales get combined to make up the essential Blues Chord Harmony. So you can get 3 Mixolydians as mentioned, or the Maj and min parallel blues scales, as mentioned or you may get a Mixolydian combined with a Minor Pentatonic on the same route note. All these methods lead to basically the same conclusion the Blues Harmony. I just think Scaler may have done this better.
My second suggestion is not based on a criticism it it just a way that may or may not improve it’s functionality. I think that it might be an idea to allow you to have a SHUFFLE FUNCTION in the Builder Section C. I think that this would be very useful. So if you have a given set of midi notes corresponding to (Bound To) notes in Section C you could experiment with this in many ways by Shuffling them up to get new combinations of Chords that you might not have thought of at first.
All in all I just love this plugin!
