Siremic B is back! ***Special re-introductory offer!! Free for a limited time only!!*** Please be sure to rate and review. Thanks! Siremic B (pronounced "Ceramic Bee") stands for Simple Remote Midi Controller (Buttons) -- and that's just what it is: Siremic B allows you to control your MIDI software by sending MIDI CC (Control Change) messages via WiFi to your Apple MIDI enabled Mac or rtpMIDI enabled PC (both your iPad and your Mac/PC must be on the same network or, in the case of a Mac, may be connected via an ad hoc network -- see setup details below). Literally at your fingertips, 40(!) customizable toggle buttons, 7 knobs and 2 faders are ready to jump into action. Freely assign any CC numbers and manage your presets. This button-centric setup makes Siremic B your perfect app for plugging in various sounds at the push of a button -- just like a virtual organ (and as a matter of fact, Siremic B was extensively tested connected to a pipe organ software instrument created in Native Instruments' Kontakt 5 sampler). Knobs and faders can be used from anything from controlling volume or panning to whatever your heart desires (and the software you control allows). ************************* Mac setup: 1a. Make sure that both your iPad and your Mac are on the same network and that your network setup allows the transmission of Apple MIDI packets. 1b. If the network you're on doesn't allow the transmission of Apple MIDI packets, don't panic. Siremic B works just as well when you create an ad hoc network between your Mac and your iPad. Here's how: i) On your Mac, click on the Wifi symbol in the top right corner of your desktop and select "Create Network…". Set up a network name, channel and security to your liking and click "Create". ii) On your iPad, launch Settings. Then go to "Wi-Fi" and under "Choose a Network…", you should see the network you just created on your Mac. Tap on it. 2. Launch Siremic B on your iPad. 3. Go to "Launchpad" on your Mac, select "Utilities" and then "Audio MIDI Setup". If you don't see the MIDI window, go to Window and select "Show MIDI Window". Click on the Network icon. In the MIDI Network Setup window, make sure that your Bonjour name matches that of the network. 4. In the Directory List, you should see your iPad. Click "Connect" to establish a session. Your iPad's name should now show up in your Participants list. Play around with the controls in Siremic B. If everything is set up correctly, you will see red lines appearing in the black Latency bar (they are more easily visible if you use the knobs or faders, as Siremic B sends multiple values). That means that your Mac is reading Apple Midi Packets correctly. ************************* PC setup: 1. Make sure that both your iPad and your PC are on the same network and that your network setup allows the transmission of Apple MIDI (rtpMIDI) packets. An rtpMIDI driver can be obtained from http://www.tobias-erichsen.de/software/rtpmidi.html *. To test the connection and data transmission between your iPad and your PC, a network protocol analyzer that can read rtpMIDI such as Wireshark may come in handy, available at wireshark.org * 2. Launch Siremic B on your iPad. 3. Launch the rtpMIDI setup frontend. 4. In the Directory List, you should see your iPad. Click "Connect" to establish a session. Your iPad's name should now show up in your Participants list. Play around with the controls in Siremic B. If everything is set up correctly, Wireshark will show rtpMIDI packets and their contents. Last but not least, credit where credit is due: Big kudos go out to Pete Goodliffe, whose PGMidi source files and helpful hints on his blog were invaluable in creating this project. * These websites are unaffiliated with Siremic B and therefore we cannot be held responsible for their contents.

WiDI is a control surface with an integrated step sequencer in which you create controls such as buttons, pads, knobs and faders to send MIDI events and play sequences. • CONTROL SURFACE AND SEQUENCER: A control is bound to a channel and a specific MIDI Control Change. You can either specify the CC number if you know it, or let the app learn it. Once placed on the surface, use this control to interact with your MIDI device. Alternatively, any CC event sent by your device will be shown live by the control(s) bound to this CC. Pads are special controls: they can either produce MIDI CC events, Notes or Program changes. If bound to a CC, the pad can act as an on/off switch (you specify the values for each state.) If bound to a note, each tap produces the specified MIDI note. This is especially useful to operate MIDI instruments without keyboards such as synthesizer modules or drum machines. A sequence can hold as many tracks as you wish, and send notes to different MIDI channels. Sequences can play in sync or running freely. You may also group sequences together to start or pause them at the same time. • MIDI: To interface WiDI with any MIDI instruments/devices connected to your Mac or PC, connect to a MIDI Network Session on your Mac or your PC. On a Mac, this is natively supported by macOS, and you do not need to install third party software (use Audio MIDI Setup.) On a PC running Windows, you might want to install rtpMIDI. As an alternative to MIDI Network Sessions, you may use the WiDI Desktop Application. It acts as a MIDI bridge between the network and your MIDI hardware. You can install the desktop application on as many computers as you want (it's free!). It's a very lightweight package that doesn't need to perform any installation procedure whatsoever. You may download the WiDI Desktop Application for macOS on the Mac App Store, or go to : https://www.hypertide.com/widi/ for both macOS and Windows archives. Additionally, any class-compliant MIDI interface natively supported by iOS can also be used directly by WiDI without the need of a network connection. • FEATURES: ○ Use any CoreMIDI-supported MIDI interface connected to your device ○ MIDI network session: use WiDI as an external control surface for any DAW such as Logic Pro, Ableton Live, Cubase, ... ○ Multiple iPhone and iPad can connect to your computer, allowing different control surfaces simultaneously ○ Integrated step sequencer: create sequences, each one holding as many tracks as needed ○ Sequences can run freely or in sync and start simultaneously if grouped together in fire groups ○ Auto discover MIDI CC : you don't need to know each one to add controls, WiDI learns CC numbers sent by your devices ○ Automate CC : sweep ranges or use the step modulator to design patterns to modulate controls values, supporting various advanced options like step-by-step or smooth variations, bouncing, repeating, changing speed ○ Add as many pads as you want to generate MIDI Notes, Control Changes or Program Changes ○ Flexible control surface : set layout and grid size for both portrait and landscape orientations ○ Re-arranging controls is as simple as drag & drop ○ Fully customizable user interface : themes, colors, display of values and labels, aspect ratios, grid spacing, grid coloring, background, ... ○ Integrated File Manager to load and save your surfaces, which are also accessible in the iOS Files app and your computer's iTunes connection ○ Exchange surfaces between devices with the integrated QR code generator and scanner ○ Or use the share feature, so you may import them on any device. We'd love to hear from you! Should you be in need of support or eager to request a new feature, please contact us at support+widi@hypertide.com
