## What is MIDI Strummer AUv3 Plugin?

MIDI Strummer is an AUv3 plugin designed to simulate guitar strumming and picking techniques. It can used to generate MIDI note data which can be sent to either an external synth of choice or the internal soundfont engine. 

The inbuilt soundfont player allows you to import all your favourite .SF2 and .DLS soundfonts and use them as a sound source. MIDI strummer has a set of 16 definable chord pads that can hold a series of chords, which in turn can be triggered remotely via MIDI messages or by tapping the pads.

Use the pattern editor to create a series of picking or strumming patterns that can be tranposed to the selected chord pad. 

Song mode allows you to chain these chord patterns together to form songs combining both picking and strumming patterns within the same song. Enable 6/12 string on a particular part to emphesize a pert by adding depth.

Strummer also features a number of audio effects that can be used to enhance the audio from the soundfont player. These include overdrive, distortion, tremolo, chorus, phaser, graphic EQ, digital delay and reverb.

Key Features:

• 6 and 12 string emulations.
• Simulate strum up/down with variable speeds.
• Create patterns up to 64 steps in length.
• Load up to 6 pattern variations.
• Ramdomize and rotate options.
• Songs can be up to 255 steps in length.
• Built in ARP function.
• Import your own soundfonts.
• 8 different effect types (reverb, delay, phaser, chorus, overdrive, distortion, tremelo and EQ).
• Paramter Automation from your DAW using MIDI.
• Built in Sampler.
• Comprehensive Help pages included.

Please Note: This version is now compatible with GarageBand running on iOS14.

### 2/5 — App Support is not opening

*2025-06-06*

How to contact the developer? Pattern length 3, 5, 7 need to be included

### 1/5 — App support web site is gone!

*2025-01-31, version 1.20*

Their app support link dumps you to done commercial demain. Just go away. You’re an embarrassment. There isn’t a 4Pockets.com other than a white blank and in tiny, yony font: “No input file specified.”

### 5/5 — Yes sir!

*2025-01-28*

Combine this with Geoshred, and better soundfonts, and you are in acoustic heaven!!!

### 4/5 — Crash

*2024-07-16*

App keeps crashing being hosted in AUM on iPhone 15 pro max. Tried to get support but the web page that comes up looks suspicious. Not even using the internal sounds. Since I am using my phone I put it into airplane mode as I am getting alerts about a storm. It seems to be ok after that. Very useful app so I hope that is the issue.  Wish there was a way to have piano to guitar chords and also be able to strum manually.

**Developer response:** Thanks for the great feedback. Checkout my tutorial videos on YouTube which can be found on the 'Paul the MusicMan' channel. This is where I get into more detail than I could ever do using the help.

### 3/5 — Good at what it does, but could do more

*2024-04-06*

When making songs with a straight bpm, the strumming is serviceable especially with effects like random velocity and humanize which can add more realism so to speak to a performance.

But as far as any song with a swing/triplet tempo with any sort of specific version of such, this program can’t do anything like that at all. Compare this to how logic pro for ipad allows one to offset each note in its pattern editor. I think it’s a wasted potential that strummer doesn’t allow you to do this too, to have that much more control over songs

### 4/5 — Crashes so much

*2024-01-15*

i love this app and it has excellent sounds but i can’t have like more than 2 tracks of this plugin open in garageband before it corrupts the entire track and makes the project impossible to open and the plugin just does not work. Please fix this soon as i love using this plugin but i just cant if it keeps glitching out like this

### 5/5 — Amazingly versatile guitar arpeggiator!

*2024-01-03*

The more I use Strummer, the more it becomes a go-to guitar player in my AU hosts. In addition to playing patterns with touch pads, it will also convert incoming MIDI to guitar chords which can be arpeggiated. You can also send Strummer’s MIDI out to play another sound module. And, it’s a capable soundfont player, so you can load other sounds. 

Song mode lets you construct a chord progression and have it play back in sync with your host. 

👍

### 3/5 — Wonderful app but…

*2023-12-16*

…it crashes constantly when used in AUM.

### 1/5 — What??

*2023-12-03*

This looks like it will take a midi composition and strum or sequence it (like phrasebox vst). If you’re looking for this, don’t waste your money. This will only sequence and arp the chords built into the app. Midi input is just to trigger their chords. Pretty sure this app is also a repackaged version of another one of their apps I bought thinking it would do the same thing.
