Ever wished your gear could just follow the music that's playing? MIDI Pulse BPM Detecter listens through the microphone, detects the BPM in real time, and keeps sending it to your equipment as MIDI Clock and Tap Tempo CC. Sync your delay pedals, arpeggiators, drum machines and loopers — no more frantically tapping along to the track. LISTENS AND DETECTS • Fully automatic beat detection from the microphone • Auto mode analyzes Low / Mid / High / Full frequency bands simultaneously and picks whichever hears the beat most clearly — kick-heavy tracks and hi-hat-driven grooves both lock in automatically • Or pin detection to a specific band: Kick, Snare, or Hi-Hat • Customizable detection range (60–200 BPM), 2x BPM mode for double-time output • One-tap manual tempo setting with tap tempo SEE WHAT IT HEARS • Beat markers on the live waveform show exactly where each beat was recognized • Optional detection envelope overlay reveals what the detector is actually analyzing • Flash lamp blinking in sync with the BPM • Real-time waveform and level meter MIDI OUTPUT • MIDI Clock transmission (24 PPQN) • Tap Tempo CC messages (customizable CC number and channel) • Bluetooth MIDI support — connect to your gear wirelessly • Auto-gain keeps detection stable even at low volumes (up to 30x) BUILT FOR THE STAGE • Settings save automatically and apply instantly • MIDI send / beat detection indicators • Pause and resume anytime In the DJ booth, at rehearsal, on stage: stop matching tempo by ear and let the phone in your pocket handle it.

deriva is a tape machine plugin that is meant to give a polished and warm silky sound on your mix or master bus. built on published research papers¹ and my own experience recording with analog tape in studio, the sound is true to how real tape actually sounds. although the engine under the hood is advanced and complex, the controls are meant to be simple and easy, so you can set and forget and focus on your music. a fun feature is that you can pull the tape while the audio is running, causing the pitch to go up or down. the controls are pretty much self-explanatory: input and drive control how hard the signal and saturation will be. also sounds great on drums! bias simulates everything from a badly aligned machine to a brand new and serviced one, together with wear. a common misconception is that there is a lot of wow and flutter on tape machines. most professional tape machines do not have much flutter and wow, but in deriva you can push the machine a bit if you like - now with separate controls. tape speed affects the sound of the tape, where the lowest is dark and the highest is studio clean. if you want to bring back some of the high frequencies lost in tape speed, you may use the tone knob next to it. if you're bored with the UI you also have the possibility to change the colors and invert them. ON THE IPAD deriva is an Audio Unit (AUv3) and works with Logic Pro, GarageBand, AUM, Cubasis, Loopy Pro, Drambo and the rest. the standalone version either works as a live effect for your instrument, but also as a tape machine player: load in your own song and listen to it "on tape". you may also record live, or export the whole song with your current settings. Requires iPadOS 15 or later. also available for Mac, Windows and Linux at eikremaudio.com. ¹ Jatin Chowdhury, "Real-Time Physical Modelling for Analog Tape Machines", Proc.
