Simplifying chords? (FM)
« on: May 10, 2017, 11:51:38 am »
I'm sure most have run into not being able to accurately reproduce full chords at some point, so what is your method of simplifying them (besides using arpeggios and 2op chord instruments)? Is there a standard practice for this that I'm not aware of?

1. Use Sine chords in Channel 3 Special mode with Algorithm 7.

2. Use Special Mode with Algo 4 to get FULL 2op chords of any pair.

3. Use PSG to complete the highest notes of full chords like in this Dynamite Headdy track:

4. Build your drum, bass, and hi-hat track using a single FM channel. Then use sampled chords in DAC when appropriate.

These are some things I do, though some of these are foundational techniques which may require you to rebuild your song from the ground up.

Those are good tricks to not simplify the chord, but I'm talking about when you do have to. For example if you want to keep extra channels for echo on the lead, backing arpeggios etc.

If you have a C major chord (C, E, and G), it seems the standard procedure is to remove the middle note if you only have a couple of channels to work with and not using the arp effect. But for different, more complex chords you can lose what makes it sound unique.

Regarding point 4 though, do you have an example track of that? Sounds interesting. I've been able to do bass, bass drum and sine waves in channel 3 (see my can can bunny extra cover), but not hi-hat and snare too. I've seen an example of bass drum, snare and hi-hat using 1 instrument though IIRC, just modifying the levels as the pattern plays.

Remove the part of the harmony already covered by the bass. That's always the most expendable tone. If you want a C major and the bass is already playing the C, then removing the middle note (E) is the last thing you want to do since that's what actually makes up the major harmony. Otherwise you'd just end up with a neutral sounding fifth.

Hi Alianger,

I sent you a PM with a WIP I'm working on. It shows an example of what I'm talking about.
