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.

Finally! AUv3 Midi from a Guitar Interface & Sequencer

Coming from a guitar background this app has got me beyond excited. I can now use a guitar interface to input chords or notes on a fretboard then arp/strum/pluck/mute them in the sequencer. Now with the new addition of custom chords (Thank you for adding that so fast Paul) This is compositional heaven for me. I’m in love with this thing.

I highly recommend this app to everyone. Even if you have no guitar knowledge, or you’re a player at any level. It’s a great way to interact with midi. Strummer midi out can trigger not only some great guitar playing, but it is equally effective with synth, keys, and anything else you want to use. Everything sounds so good with midi generated from Strummer. Another 4Pockets masterpiece. What an amazing app! 6 Stars.

Not working as an Audio Unit plugin for GarageBand iOS 14

I’m attempting to use this to trigger(as Audio Unit) the soundfont library in the app (the sounds are terrific), but all attempts to get a stable MIDI connection have failed and attempts to use the app for Inter-App Audio input have likewise resulted in crashes repeatedly. Please fix this because this app is exactly what I’ve been searching for to speed up my audio production process. Thank you.

Developer Response ,

There seems to be an issue running this app on iOS14 in GarageBand. I'm not sure what is causing the issue right now but I am looking into the problem. It seems to be working fine on iOS13, but not 14. After taking some time looking into this I am forwarding the relevent information through to the GarageBand team to take a look at as I'm not sure the problem lies with Strummer at this point in time.
