Freeware MIDI-related software utilities abound on the Internet; some of my favorites are described in detail here. Each section includes ascreencast video to illustrate how to use the utility.

Mf2t / t2mf

Standard MIDI files are binary files, and therefore cannot by read using a standard text editor. Piet van Oostrum has developed a companion pair of console applications called mf2t (MIDI File to Text) and t2mf (Text to MIDI File) that translate back and forth between the standard MIDI file and a human-readable version. You can more easily study the text-version MIDI file to see the messages, meta-events, and timing information. Also, you can edit the text-version, and then convert it back to the standard binary format.

Created by Christian Maas, XVI32 is an excellent binary file editor (or“hex editor”) when you need to view a standard MIDI file directly. XVI32 can also modify the file by tweaking individual byte values, or by inserting and deleting ranges of values. The editor also includes tools to interpret data values, i.e., select and range of 8 bytes and interpret as an IEEE double-precision floating point value.

MIDI-OX is a wonderful utility developed Jamie O'Connell and Jerry Jorgenrud. MIDI-OX serves as a MIDI protocol analyzer by displaying MIDI data streams in real-time. MIDI-OX can also filter MIDI streams (remove selected message types) and map MIDI streams (change selected message types according to some rule). MIDI-OX includes other useful features: you can use your computer’s keyboard to generate note events (you can even hold down multiple keys to play chords!), you can play standard MIDI files (.mid files), and you can capture a MIDI data stream and save it to a file.

In order to make full use of MIDI-OX, you will also want to install the MIDI-Yoke driver. MIDI-Yoke works like a virtual MIDI patch bay , a device that connects MIDI inputs and outputs together. For example, you can connect the output of a MIDI sequencer application to MIDI-OX to view the MIDI messages, and then send the message to the MIDI synthesizer on your soundcard. When you have many MIDI-capable devices connected to your computer, MIDI-OX and MIDI-Yoke make it easy to quickly re-configure the virtual connections without changing any external cables.

JAZZ++ is a MIDI sequencer created by Andreas Voss and Per Sigmond. JAZZ++ serves as a multi-track recorder and editor for MIDI-capable instruments, and also supports audio tracks. A musician can create a composition with full instrumentation by recording tracks one at a time. Performances such as a piano solo recorded by the sequencer can easily be edited to correct any mistakes. JAZZ++ is also a great way to graphically visualize the contents of a standard MIDI file.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
