This is a tool for MIDI experts. Not recommended for beginners. - This app by itself does not produce sound. - It converts input MIDI signals and outputs them. - You can use 8x16 pads to output any MIDI signal. - You can route MIDI devices freely. - This app includes 2 AUv3 Plugins. - Compatible only with MIDI 1.0; MIDI 2.0 is not supported. - The developer uses this app conveniently with a MIDI wind controller. Convert Converts the values of control signals. Cannot be set per channel. Note Ctrl, Threshold: Transmit note on messages only if the value of the Note Ctrl is above the threshold. Key: Key of the note signal Vel1: Velocity of Note On Vel0: Velocity of Note Off CC: Control Change AT: Channel Aftertouch PB: Pitch Bend PC: Program Change N/A: Not applicable HR: High Resolution - when enabled, handles 14-bit signals. E: Envelope, tap to open the settings window. F: Filter, tap to open the settings window. LPF: Low-pass filter, smoothes out value changes. The higher the Strength value, the slower the change. HPF: High-pass filter, applies only abrupt value changes. The value automatically approaches the Return Base value. The higher the Strength value, the faster the change. Tap the graph to switch between line graph, history, and bar graph. Long press the graph and tap “Edit Curve” to edit the curve. "- 0 +" denotes the offset; this value is added to the input value. Press the button in the top left corner to switch to a minimized view. The "!" in the top right corner is the panic button. Pressing it sends All Notes Off and All Sound Off messages. Trigger Sends signals according to the rules upon receiving specified MIDI signals. You can specify channels. Harmony: Shifted note signals Channel Rewrite: Rewrite of channels Signal Trigger: Trigger of any MIDI signal Value Offset: Increment/decrement of value Filter: Suppression of transmission Pad Consists of 8x16 pads. Note: Note signal CC/AT/PB Oneshot: Control signal (when pressed) CC/AT/PB On/Off: Control signal (press/release) Program: Patch Change (bank selectable) Convert Offset: Offset specification for the Convert screen Load Preset: File loading on the Profiles screen Misc/SysEx: Any signal Latch: Pads become toggles. If a group is specified, the pads act as radio buttons. Options Key Delay: Delays Note On Velocity Convert: When outputting Vel1 in Convert, select whether to always convert or only when legato is not present MIDI Rx Channel: Receiving channel MIDI Tx Channel: Transmitting channel Filter Other Channel: Suppress transmission of channels other than receiving channel Duplicated Notes: Specifies handling of duplicated notes Note that: The application and description contain machine-translated text.

Read full description

Breadbin is a Commodore 64 emulator for iPhone, iPad and Mac — written from scratch in Swift, every chip built from the original hardware documentation. Not a port, and not a wrapper around somebody else's emulator, original code from the first cycle to the last. YOU BRING THE ROMS Breadbin ships clean — no ROM images and no games, because they are not ours to give away. On first launch the app lists the three system files the machine needs (KERNAL, BASIC, character generator), shows which ones it has found, and imports them with a tap from the Files app. Dump them from hardware you own, or use freely licensed replacement ROMs — either way you are a minute from a READY prompt. Your files stay on your device. ACCURACY YOU CAN CHECK • Cycle-accurate 6510 processor — undocumented opcodes, NMOS decimal mode, per-cycle bus behaviour. Passes Klaus Dormann's 6502 functional test suite, the standard the emulator community measures against. • Cycle-based VIC-II video — bad lines, sprite DMA, the border unit, all eight graphics modes, raster interrupts. Raster-timing demos behave the way they should. • A real 1541 drive — its own processor, its own VIA chips, a rotating GCR bitstream with byte-ready wired exactly as the hardware does it. Fastloaders and copy-protected disks work here instead of hanging. • Both SID sound revisions, 6581 and 8580, built from the datasheet — including the mixer quirk that makes 4-bit sample playback audible on the 6581. DIAL A BULLETIN BOARD Breadbin carries an emulated SwiftLink modem bridged to the internet. Run a terminal program, pick a board from your phone book, and you are logged into a live BBS over TCP — telnet negotiation handled for you, PETSCII intact. The boards are still out there, and still busy. Your phone book is a plain text file you edit yourself. BUILT FOR THE DEVICE IN YOUR HAND • A touch keyboard laid out like the real machine, with national keycaps for Sweden/Finland, Denmark/Norway and Germany • On-screen joystick — analog stick or D-pad, placed where your thumb actually is, with autofire • 1351 proportional mouse — a trackpad on touch screens, a captured pointer on the Mac • Save states with thumbnails, so you can put the machine down mid-level • Display filters from razor-sharp pixels to a softened CRT look, with an adjustable border • Instant loading when you want it, true drive speed when the software demands it • Loads .prg, .d64, .g64, .t64, .p00 and .crt cartridge files • One purchase covers iPhone, iPad and Mac PAY ONCE, PLAY FOREVER No ads. No subscriptions. No in-app purchases. No account. And no data collection: no analytics, no tracking — nothing is collected, so there is nothing to sell, share or leak. The only network traffic Breadbin ever makes is the bulletin board you tell it to dial. Breadbin is not affiliated with, authorised by, or endorsed by the owners of the Commodore or Commodore 64 trademarks. It ships no Commodore software.
