It allows efficient USB protocol analysis for High Speed USB 2.0, SuperSpeed USB 3.0 and SuperSpeed+ USB 3.x communications.įor the best user experience, our product supports data filtering. It runs smoothly, processes monitored packets in real-time even on high data rates (up to 20 Gbit/s). This Freeware USB data snooping utility requires no additional hardware or cables to operate. Our USB monitoring program may be an excellent alternative to hardware analyzers because it intercepts all Windows API function calls which are transferred between USB applications and device drivers, parses transmitted packets and shows all captured data in a several convenient forms, which is virtually impossible for hardware solutions due to their low level view. All Windows desktop/server 32-bit and 64-bit platforms starting from Windows Vista are supported. This software-based USB protocol analyzer allows you to monitor the data transferred between USB applications and devices connected to your computer via USB interfaces. On = MIDIFunc.Free USB Analyzer is a non-intrusive software USB sniffer and protocol analyzer for Windows. Notes = Array.newClear(128) // array has one slot per possible MIDI note The technical problem is that every note on needs to save its synth object so that the note off message can end the right server-side node. The exceptions are sysex (system exclusive) and sysrt (MIDI clock) messages, which are currently supported only by MIDIIn. It is generally recommended to avoid using MIDIIn directly. This means, for practical use, MIDIIn is significantly harder to use than MIDIFunc or MIDIdef. Note, however, that MIDIIn provides no functionality for filtering incoming MIDI based on device, controller number or other factors. Technical details on each function can be found in the MIDIIn help file. MIDIIn has a number of class variables holding functions to be evaluated when a MIDI event comes in. For example, you may want one MIDIFunc to handle controller 1, while a different MIDIFunc handles controller 7.įilters are set by the argument immediately following the response function: MIDIFunc.incomingType(.uid.Īny filters that are omitted will match all values - e.g., for an omni-channel responder, simply leave out a chan filter. MIDIFunc and MIDIdef can filter incoming messages, responding to specific devices, MIDI channels or data values. MIDIFunc and MIDIdef: Filtering based on device or message data See Playing notes on your MIDI keyboard below for a simple example using the note-on and note-off MIDIFuncs. It can filter incoming MIDI messages to respond to a particular device, channel number, or specific message number, or ranges thereof. MIDIFunc has a number of convenience methods allowing you to register for the different MIDI message types. The advantage of this approach is that any number of responders can be registered, using extremely flexible matching. Receiving MIDI input MIDIFunc and MIDIdefįor most uses, the preferred way to receive MIDI input is using the MIDIFunc and MIDIdef classes. In most cases, each physical MIDI connection (pair of in/out jacks on the MIDI interface) has one MIDIEndPoint object to represent it in the client. It is strongly recommended to avoid using this class directly. MIDIFunc and MIDIdef use this class so that you don't have to. MIDIIn The lowest-level MIDI input class.
It contains a device name, port name and unique identifier (uid). MIDIEndPoint Represents a MIDI port published by the operating system. MIDIOut Supports MIDI output to hardware ports or inter-application MIDI buses. Especially helpful for live or interactive use. MIDIdef Related to MIDIFunc, this class keeps several MIDIFunc objects in global storage, by name. MIDIFunc The optimal way to receive the most typical MIDI messages: note on/off, controller, pitch bend, aftertouch, poly-touch and program change. See the example Playing notes on your MIDI keyboard. MIDIClient must be initialized before MIDI can be received. The information about the hardware is stored in MIDIClient.sources and stinations as MIDIEndPoint objects. The main MIDI classes are: MIDIClient This class connects to the operating system's MIDI layer, and obtains the lists of available MIDI sources and destinations. All MIDI devices accessible to your operating system (CoreMIDI on macOS, ALSA on Linux, PortMIDI on Windows) are accessible to SuperCollider. SuperCollider's out of the box MIDI support is fairly thorough (although not as complete as you'll find in commercial sequencers). See also: MIDI, MIDIFunc, MIDIdef Introduction
