Midi is a complete package for SEGY & SEGD data manipulation, transfer, and quality control (QC) from disk, tape, or FTP. Midi allows you to build your own seismic Table of Contents (TOC), to ensure that your data fully complies to your own custom standards. These TOC capabilities can ensure that the correct data is populated throughout the trace headers, and can highlight any gaps found immediately.


Midi is fully capable with the latest SEGD rev. 3 updates from the SEG Technical Standards Committee. Many national oil companies are now requiring that data is shot in SEGD rev. 3, and Midi can ensure the data complies to all standards; Midi can also update historic libraries from previous SEGD revisions. 


Troika has developed a highly efficient SEG-D copy utility within MIDI. This crucial software provides the necessary tools to standardize your entire SEG-D library and transfer data from low-density, typically 9 track, 3480/3490 or 3590 to high capacity media (such as 3592). This package embraces the new SEGD 3.1 format which records a sequence number for each seismic line within a survey so that multiple lines may be written to tape.



MIDI can be interfaced to any standard SCSI devices via IBM/Windows drivers and "off-the-shelf" controllers including:

  • 9-track: 3480, 3490, 3490(E), 3590, 3592
  • Exabyte: 8500,8505, 8700
  • DLT
  • DAT
  • DVD
  • CD

etc. Multiple drives may also be attached and run as separate job streams to increase throughput. MIDI includes support for a number of robotic devices including IBM3494 and STK9710, and also supports customized uploading of metadata to databases via XML



A number of lists are created whilst transcription is being carried out, which may be used for quality assurance purposes, saving to disk, printout, etc. These lists include details of the data that has been read from and written to tape providing a machine-readable listing for import to a database, spread sheet for labeling, or documentation such as transmittals.
