Demo Video of Monster OctaChord

Stamatis Stabos made a cool walkthrough of Monster OctaChord’s presets using his 2-octave Arturia Minilab MIDI Controller and and Behringer TD3 RD6 :

Why The Size of MONSTER OctaChord is So Big and No MIDI-OUT Feature?

This plugin is a ROMPLER and consists of 18 presets, each containing 12 scales. Each scale is comprised of 15 files, 8 for chords and 7 for ornaments. Assuming each chord/ornament file is stereo and in 4 MB in size, with a sample rate of 48 kHz and a bit depth of 24 bits, here’s the calculations:

18 presets x 12 scales x 15 stereo files = 3240 stereo files
3240 stereo files x 4MB = 12,960 MB = 12 GB of files
However, I have optimized some presets, so the plugin size is smaller (still 6GB after unzipping).

Initially, I designed each preset to have only 1 or 2 scales, such as C Major and G Major. However, I realized that users may want to create music in other keys as well. That’s why I included all 12 scales to provide greater flexibility.

I am a full-time music producer, and I have developed this plugin as a hobby, offering it for free. Since I am not a professional programmer, my current software has limitations in reducing its size. Since this is only version 1, perhaps in the future, I will explore different programming software that includes a built-in MIDI player, which could result in a smaller file size and maybe a MIDI-OUT feature so user can have their own virtual instrument plugins. I’m sorry this version 1 doesn’t have those features!

So, that’s the reason behind it (Regards, Agus Hardiman of MonsterDAW)

How To Automate Monster OctaChord Parameters?

In Cubase, after inserting the Monster OctaChord plugin, you have to open the automation lane (I’m using Monster Synth as the example):

In Studio One, go to the Piano Roll and add the parameters to automate (I’m using Monster Synth as the example):

FAQ About Monster OctaChord

Q : I want XXX and YYY features of Monster OctaChord, can you program it?

A : To be honest, I’m a professional musician and audio educator BUT I’m not a professional plugin programmer. I do this just for fun, so your request may not be available (but you can always try to ask me via the CONTACT page).

QI chose the wrong folder library and my Monster plugins show up with a different library. How to solve this?

A : Move the wrong library folder to somewhere else on your hard disk and start the plugin again. It will ask for the new folder location. Now, choose the right one. You can move back that 1st folder to its original location after the plugin loads the correct library.

Q : Why there are no VST 32-bit versions anymore?

A : In the past, I made a 32-bit version of my VST. But now my programming software CAN’T output 32-bit plugin anymore, so I’m not providing 32-bit.

Q : I have a problem using this plugin on my Mac, I’m using Monterey/Big Sur/Catalina. It says that the files are damaged or can’t be opened because the developer is not trusted.

A : That problem was caused by Mac OS security which is now very strict. I have applied for a developer account in Apple to be a trusted developer but they haven’t responded to my inquiry yet.

In the meantime, please watch these videos (If this is not working, it’s ok, you can pass my VSTs ?):
