24 Track 24 Bit Hard Disk Recorder

Front Panel Editing: No Computer Required

You don't need a computer, a monitor, a keyboard and a mouse to edit your audio on the MX-2424. At the same time, you're not limited to just cutting, copying and pasting your audio. Here's a list of editing controls that are all accessible from the MX-2424's front panel alone: Cut, Local Cut, Left Cut , Left Local Cut, Copy, Paste, Paste Left, Multi Paste, Paste at Playhead, Clear, Open, Insert, Multi Insert, Split, Discard, Sync Paste, Sync Insert, Nudge Left, Nudge Right, Render, Redo, Undo , Reverse.
The controls on its front panel allow you to flexibly edit tracks while keeping your mind on your music and audio. You'll also appreciate the MX-2424's built-in editing tools in the field, where you don't want to lug a heavy monitor. If you've recorded the perfect backing vocal tracks, it's easy to Copy and Paste them to the next couple of choruses. Or, copy a measure or two of drum grooves and Multi-Paste them into the rest of your song. With a few button presses, you can Insert an entirely new bridge between the second chorus and the third verse. Got a solo passage that's timed in a strange place in the measure? Sync Paste it around your song as desired. The possibilities are virtually endless. The MX-2424's front panel editing is done by capturing edit points, fine tuning them by scrubbing the audio and performing the edit on whatever tracks you choose. If your first try at an edit doesn't sound quite like you expected, there are 100 levels of undo/redo that let you get back to where you were before.

MX-View: on board editing software graphic interface

MX-View is a brand new editing interface for TASCAM's MX-2424 . Offering a sophisticated graphic editing interface that's comparable to full-featured digital audio workstations, MX-View lends powerful editing capabilities to the MX-2424. Running natively on both Mac and Windows platforms, MX-View was custom designed specifically for the MX-2424. MX-View is a quick and responsive editor, with the ability to view waveforms down to the sample level. You can repair clicks and pops with the pencil tool, select and nudge audio events to the correct beat, drag and drop audio files with the hand tool, fade, crossfade and trim events on the fly. In addition to replicating the extensive front panel controls of the MX-2424, MX-View offers a slew of new features and capabilities based on its standard 100 Megabit Ethernet interface. MX-View allows you to transfer individual and groups of audio files to your computer and back, as well as letting you back up entire projects. The MX-View interface also functions as a complete system interface for as many MX-2424s as you wish. Multiple MX-2424s can be displayed and edited on the screen simultaneously, there's no need for a separate monitor for each machine. Plus, each machine's meters can be clearly seen from the MX-View windows, making it a thorough remote control interface. MX-View's interface is also customizable and designed ergonomically. Buttons and windows can be hidden as needed, and color-coded edit groups makes editing across multiple track a snap. Keyboard command sets may be configured by users to their liking, and windows like the transport, locate markers, and level meter can be moved around freely and stored as a user preference.

File Types and disk drives for compatibility everywhere

Why do you need to have a recording/editing system that's compatible with other equipment? There are several reasons. You may have a preference regarding other audio tools that offer recording, processing and editing capabilities. Example: you like to work in the realm of your favorite computer-based audio system but want to track using the MX-2424.
You may need to work in different environments with different equipment during the process of recording, editing, mixing and mastering your music. Example: you want to record the basic tracks in a tracking room but take the audio to your personal studio for vocals and overdubs. Or, you want to edit and mix on a DAW but don't want to lug a whole computer into the field for location recording.
There are two main factors to compatibility in hard disk recording systems. First what type of audio files it creates. Second, and perhaps most important, is the type of hard drive the recorder uses.
Every hard disk recorder writes a particular type of audio file format to its particular format of hard disk. Instead of some proprietary system that won't be able to be used outside of the recorder, Tascam have chosen two of the most popular formats for use in the MX-2424: Sound Designer II for Mac formatted disks and Broadcast Wave (compatible with .wav files) for PC formatted disks. Using these formats, it's easy to move your audio files from the MX-2424 into audio editing systems on Macintosh and Windows computers, like Digidesign's Pro Tools, Mark of the Unicorn's Digital Performer, Steinberg's Cubase and more. Plus, any system that's compatible with SDII or Wave files will allow you to import your MX-2424 audio files. If that system supports time stamped audio files, they can be placed at their original time code location with sample accuracy.
Since you can choose directly to either SDII or Wave file formats, you'll stay compatible with DAW systems like Pro Tools, Digital Performer, Nuendo and other software-based system for both Mac and Windows.

SCSI Hard Drives

Why SCSI drives for the MX-2424 ? At 24 tracks, the demand for sustained speed in reading/writing files to disk is critical. The MX-2424's SCSI architecture lets you perform functions like seamless punch ins/outs on all 24 tracks at once and playing across sections with high densities of editing, which may not be possible with other drive formats. SCSI drives are also very robust. Though every hard disk recorder should be backed up to media other than hard drives, the internal Quantum Atlas V drive is rated for 300Gs of impact. Perhaps the best reason for going with a SCSI-based hard disk recorder is its compatibility with other systems. The MX-2424 lets you choose to format its hard drives for specific compatibility with Mac or PC. You could take a drive from the MX-2424, connect it to a compatible computer, and access the audio data in your computer editing system , all without powering down your system if you are equipped with a hot-swappable drive system. Plus, an MX-2424 project has files and folders so you can copy selected audio files (or an entire session).

MX-2424 Interfaces and Peripherals

Including 24-channel interfacing for analog, TDIF, ADAT and AES/EBU and the RC-2424 remote control surface.

Unless you can flexibly route your audio and data around your studio, your hard disk recorder might as well be a doorstop. The MX-2424 provides plenty of options for getting analog and digital signals to consoles and other studio tools. It even allows you to send and receive digital and analog signals simultaneously.
Backing up hard drives is one of the most important parts of doing hard disk recording. The MX-2424 offers a variety of audio interfacing options. All of the MX-2424 I/O options offer a full 24 channels of interfacing, and you can choose between analog and a variety of digital interfacing protocols such as TDIF, ADAT Optical and AES/EBU. Connecting the MX-2424 to any digital or analog console as well as popular digital audio recording/editing systems is easy. On the MX-2424, you can use both the analog and digital interfaces simultaneously. Using this versatile routing, you could record through the MX-2424's analog converters and monitor via a digital console. And with the exception of the ADAT Optical Interface, all MX-2424 I/O cards support 96kHz sampling rates.

Designed for studios in which multiple MX-2424s will be put into use, or studios in which the MX-2424 will be kept in a separate machine room, the RC-2424 Remote Control Surface offers control of up to 6 MX machines from up to 100 meters away. It also has special macro features for commonly repeated tasks.

MX-2424 Backup Solutions

Though hard disk recording offers amazing creative advantages over tape-only systems, hard drives themselves are vulnerable to physical damage. Even the world's sturdiest drives, like our Quantum Atlas V drives that are rated to handle 300Gs of impact, are susceptible to losing an album's worth of material from an accidental drop on a hard studio floor.

The backup options
A 2X high-capacity DVD-RAM drive may be installed in the front bay of the MX-2424 or connected to its rear panel SCSI port for backup to a reliable and easily transportable archive format. DVD-RAM has already been accepted as a robust storage medium by the demanding computer industry. In addition to the benefits of being a secure archive and transfer format, DVD-RAM disks represent a substantial long-term cost saving over hard drive-only backup.
