Hi @Bsac109. You have a lot of questions there. Let me try to address them all:
It appears scaler is the only app that actually offers both piano and guitar interfaces?
I don’t know if it is the only one, however the main instrument panel in Scaler 2 can be displayed as either a keyboard or a guitar fretboard.
In addition, it appears to be the only one that can read audio chord progressions like chord icy.com plus give you the tonal center key?
I don’t know what icy.com is (perhaps a typo), however Scaler 2 has very effective audio detection capabilities and can detect chords from audio or MIDI sources, and suggest associated scales ranked by relevancy.
Anyhow, it’s my understanding that the guitar interface is not quite baked in completely. That is you can’t alter voicings or do all the things you can like the keyboard interface?
Switching to the guitar view doesn’t change Scaler’s functionality at all, so everything that is possible via the keyboard view is still possible, with the exception of per note velocity editing which needs to be done via the keyboard view. Scaler can optionally display guitar chord charts for each of your chords, however these are more for illustrative purposes and cannot be edited like the instrument panel.
This is elaborated on further in the following guitarists guide to Scaler video:
I need a tool that can do the above plus make next chord suggestions when I input chords.
Scaler has various means of suggesting chords, either via the suggest button on the main page, or various parts of the modulation page.
Does scaler have drums?
No.
Does scaler have bass?
Yes. Scaler 2 includes a variety of bass sounds as well as many bass performances covering many genres and styles.
I have many songs that need bridges or “B” sections and was wondering if scaler 2 was the tool for me?
Scaler 2 allows you to create up to 7 different patterns and name them accordingly i.e. chorus, bridge, B Section etc. These can be arranged and optionally played sequentially via pad view.
