It sounds like you are a Pink Floyd fan like me.

On MODX it will likely be "User Arpeggios".... big topic. Start reading the Manuals and searching this site.

Another way to do it, IF you are only interested in using the part to play the intro of Shine On You Crazy Diamond (Gm, Dm, Cm - all minor chords) is to create a 3 Element AWM2 Part with Element 1 tuned normally (Root), Element 2 tuned (coarse tuning) to +3 (minor third) and Element 3 to +7 (Prerfect 5th). Then get a Sustain pedal and plug it in the Sustain port.

Play a G (G minor) and sustain it. When the guitar kicks in, do the same but play the D and C where appropriate.

Tip: Choose a Synth Strings Part to begin with (3 element minor chords), and keyboard split it to only operate below middle C. Pick a second Part Synth Brass (lead sound) and split it to only play above middle C.

That should get you moving in the right direction and starting to work things out.

Hi, thanks for the answer.
Yes, you're right I'm a Pink Floyd fan, but lately I've been interested in rock blues phrasing with my band and I'm looking for solutions to better emphasize the brass. This is why I am interested in programming performances where by playing a note I get the addition of a third, a fifth, a seventh with other brass, in order to create a complete section that is as real as possible.

What I've discovered regards "Arps" i.e. Automated Arpeggios, is they are not Modal Harmonisers. You cannot set a "Key" or "Mode" to play in and let the Arps pull out the correct harmonies depending on the (single) root note you play.

The basics are, you need to at least play the chord notes you want to arpeggiate..., the obvious case is a Minor vs Major chord. For example, you would need to play (in real time) the Root + Minor 3rd or Root + Major 3rd to keep the arppegiator tracking the harmony. 4ths, 5ths and Octaves are usually OK.... the Arp can handle them because the interval stays the same (unless you want to mess around with diminished and augmented chords).

The alternative is to create a User Arp that will play a chord progression (minor to major for example), but you have to play and record it first, to a tempo, and to a time signature. You can change the tempo later... I play/record it slow, then adjust the tempo later. Arp Gate and Quantize can help you here.

An example of a User Arp I made is the violin arpeggios in the chorus of Comfortably Numb. The chords move from a Major, down a 4th to another Major (D to A for example), but the first Chord arpeggio has a major 3rd to a major 2nd movement, the second chord has a Perfect 4th to a Major 3rd movement.

What I ended up doing is recording the whole D to A arpeggio, and turning it into a User Arp. With a single note press of the D key, I get the arpeggio. When it moves to the C to G, I just play a single note C. Then my hands are free to play the other bits.

For your "Brass Hits" with 7ths it would be the same. You would either need to play the minor or dominant 7th as applicable, or, if its a common repeating chord progression, record a User Arp with that same progression and trigger it from 1 key.

I published that performance on Soundmondo, so hopefully i can help. It was a challenge i set myself in response to a previous post that was coincidentally made by Anthony, who has been kindly helping you on this issue.
The 1 note chords are made of 3 presets, String Machine, Clean (organ) and Dark Light (pad) .
For each sound i copied all elements within the part to enable chords to be played keeping the integrity of the sound
The original String Machine has 3 elements, my part has 8. The other 2 parts start with 2 elements and my parts have 6.

To see how this works, please do the following
Using category search, find the single part organ performance 'Clean'
press edit, and select 'all' in the bottom right corner of the screen. You now have two screens to toggle between, Osc and Balance, that show there are two elements used in this part: Organ Wave 1 and Organ Wave3 that are panned apart and are also one octave apart.
Using Shift + Edit copy elements 1 and 2 to 3 &4 and 5&6. It is now possible to have 6 elements per note
To create the minor chord simply edit 3&4 plus 3 semitones and 5&6 plus 7 semitones. This is part 2 of the Shine On performance

If you return to 'Shine On for Forum', the first 3 parts have all been modified in this way. The strings only slightly more complicated

BRASS SECTION
This might be fun and this is what i've done on a couple of Cover songs, 'Uptown Funk' being one. It does take up 4 parts!
Think of the brass quartet that you want. Say Trombone, Tenor Sax, Trumpet1 and Trumpet 2.
Find the single part performances you like and combine them into a multi part performance
select part 1 -edit - part settings - pitch. From here you can adjust note shift and pitch bend range for each part.

For Example
Normal: Trombone and Sax play one octave below the 2 trumpets
Pitch Bend Up: Have all 4 parts split in different directions to a minor 7th chord
Pitch Bend Down: Have all 4 parts split to a diminished 5th

There are lots of other controllers that you could use too.

Hi guys,
you have been very precise and I have already followed your instructions and obtained the expected results.
Thank you and greetings, see you next time
Sal.
